What happens in the thirteenth obstetric week of pregnancy. What happens in the thirteenth obstetric week of pregnancy 13 weeks what happens

The 13th obstetric week of pregnancy has come, when the emotional background of the expectant mother is normalized, toxicosis passes and the most difficult and dangerous time of gestation is left behind.

The placenta has finished developing, so the pressure of the expectant mother may be below normal. Progesterone is produced, which reduces the tone of the blood vessels. This facilitates the process of blood circulation between mother and child.

Progesterone also relaxes the digestive organs. Therefore, for a woman at the 13th week of pregnancy, discomfort and constipation are frequent companions. The first trimester of pregnancy ends with a significant increase in the mammary glands of the expectant mother, which are preparing for lactation. Therefore, a woman during this period may feel chest pain.

Uterus at 13 weeks pregnant

Now, most women have a significantly enlarged uterus: it continues to grow in the hip region. This important organ is now located in the lower abdomen.

Stomach

The uterus can be easily felt by feeling the belly at 13 weeks of gestation. The expectant mother gets the feeling that she has a smooth soft ball inside her. At the same time, a woman, as a rule, already begins to steadily gain weight, her belly is growing.

Fetus

At this time, the baby grows even more intensively. Facial features already have personality. Facial expressions are gradually developing: now the baby can smack his lips. The gums contain the rudiments of milk teeth.

The fetus at 13 weeks of gestation intensively develops in the nervous system. The brain is now responsible for the baby's reflex movements. Insulin is produced by the pancreas, and bile is formed from the gallbladder. The baby's vocal cords are being improved, the rib bones are strengthened.

The head begins to grow more slowly, and the body grows. The size of the fetus at 13 weeks of gestation is 8-10 cm. The skin of the crumbs develops, but it is still thin, with protruding vessels. Digestive villi have already appeared in the intestines.

In girls, ovaries continue to form, in boys, the prostate gland is improving. The yolk sac stops working, so it is often not visualized on ultrasound at 13 obstetric weeks of pregnancy.

Now the spleen and bone marrow are involved in hematopoiesis. Prior to this, this function was performed by the liver. Until the 13th week of pregnancy, the child experienced allantoid circulation through the protrusion of the primary intestine. Now the placenta will take over this function.

The baby continues to swallow amniotic fluid. According to some scientists, they smell like food that the expectant mother eats.

When conducting an ultrasound scan at the 13th week of pregnancy, the CTE no longer performs an informative function. The baby's condition is determined by:

abdominal circumference;
the length of the femur;
biparietal size.

Feel

Now comes a pleasant period for the expectant mother. She literally comes to life, because toxicosis and all the unpleasant sensations at the 13th week of pregnancy are left behind. However, not all women go smoothly: some expectant mothers still experience toxicosis. This is possible if the diet includes a lot of unhealthy foods.

Also, toxicosis at 13 weeks of gestation can continue if a woman has multiple pregnancies or physiological characteristics that favor it.

Many expectant mothers tolerate pregnancy so easily that they absolutely do not feel it. It is quite normal if the gynecologist can easily listen to the heartbeat of the baby. Sometimes painful sensations in the lower back appear at the 13th week of pregnancy, which is also quite natural. However, if the pain intensifies and is aggravated by pulling sensations in the abdomen, you should immediately consult a specialist.

At this time, the mother still does not feel the movements of her crumbs, but there are exceptions. Now the woman does not feel irritable and becomes calm and joyful. Drowsiness disappears, strength and vigor appear.

The expectant mother should understand that she has a huge responsibility. At the same time, she needs to adhere to certain recommendations.

Nutrition

Food at 12 weeks of gestation should contain a large amount of vitamins. Vitamin E is especially important. With low hemoglobin, you should diversify the menu with beef, liver, pomegranates.

Alcoholic drinks, coffee and strong tea are unacceptable. You should still refrain from salty, fatty and fried foods, even if the 13th week of pregnancy is not accompanied by toxicosis.

Eating a lot of baked goods and pastries is also undesirable for the expectant mother. Now there is an increase in her weight, and extra pounds during childbirth are extremely undesirable.

A woman needs micro and macro elements, which are found in fruits, berries and vegetables. If the expectant mother is still worried about toxicosis, then she should limit herself to the use of light foods.

Vitamins

At the 13th obstetric week of pregnancy, the expectant mother continues to drink vitamins. Their composition practically does not differ from last week. You should continue taking:

iodomarine;
vitamin E;
folic acid.

In addition, the pregnant woman should start taking calcium: now the baby's bones are strengthened, future teeth are being formed. If there is a threat of miscarriage, the doctor will recommend taking Magnesium B6.

Sex

The risk of miscarriage is reduced, and the expectant mother feels much better. Therefore, now is the right time for the heyday of the intimate life of the spouses.

A woman calmly perceives pregnancy and does not experience such fears as at first. However, if the expectant mother is feeling unwell, it is best not to risk it and give up sex for a while at the 13th week of pregnancy. Also, restrictions are introduced if there is a threat of miscarriage or a woman has multiple pregnancies.

Physical activity

If the pregnancy proceeds without problems, then at 13 weeks certain physical activity is required. Thanks to them, muscles are strengthened, good blood supply is provided. This allows the baby to receive the required amount of oxygen and nutrients.

A woman must perform gymnastics characteristic of this period. The obstetrician-gynecologist will tell you in detail about her at the next appointment.

The mom-to-be should still take half-hour walks in the fresh air. However, it must be remembered that heavy loads are best avoided. If you feel tired and tired at the 13th week of pregnancy, it is better to spend some time at rest.

Medicines and medical procedures

Various drugs and certain medical procedures are highly undesirable for the expectant mother. But if they are necessary, only an obstetrician-gynecologist can make the final decision on taking medications. You should not self-medicate, because the risk for the baby is always present.

Colds and fever

Colds at 13 weeks of gestation should, if possible, be treated with a specialist. When the temperature rises to 38 degrees, you can take a baby antipyretic, for example, Nurofen. However, you should not abuse it, and it is even better to use folk remedies. For example, lingonberry juice lowers the temperature quite well at 13 weeks of gestation.

Possible problems

At obstetric 13 weeks of pregnancy, the threat of miscarriage is reduced, and the expectant mother can breathe a sigh of relief. However, you should not completely relax, you still need to be attentive to your health.

Pain

If a woman has severe and unpleasant pain at the 13th week of pregnancy in the side and lower back, it is necessary to immediately inform the doctor about it. Also, the tension of the abdomen, pulling pains should be a cause for excitement.

If pain or cramps occur in the legs, the woman should increase the amount of calcium and potassium.

Allocations

You should still pay attention to the discharge. Yellowish, white or transparent mucus in small quantities and without a pungent odor is the norm.

Bleeding

A bloody, brown, green, or profuse watery discharge should be a reason to see a specialist. If bleeding occurs at 12 weeks of gestation, you should immediately call an ambulance.

Frozen pregnancy

Frozen pregnancy at 13 weeks at an early stage practically does not manifest itself in any way - it can be seen on an ultrasound scan or examination. At a later stage, due to intoxication of the body, weakness, nausea, spotting and high fever may appear.

And although the risk of a frozen pregnancy at 13 weeks is already quite low, pathology can be provoked by:

genetic abnormalities in the fetus;
hormonal disorders;
the so-called bad habits of the mother: smoking and so on;
developmental abnormalities and diseases of the uterus;
poisoning with vapors of harmful substances.

Alcohol

Alcohol at 12 weeks gestation can cause fetal freezing. Any harmful substances during this period should be discarded.

Tests and screening at 12 weeks of gestation

The 13th week of pregnancy means that the expectant mother is probably already registered in the antenatal clinic. Now she has to take a general blood and urine test every two weeks.

Ultrasound

If a woman has not yet undergone an ultrasound scan before the 13th week of pregnancy, then she should certainly do this. She may not know the baby's gender yet, but she will be able to make sure of the correct development of the baby.

Features of IVF pregnancy

On ultrasound, the specialist will conduct anthropometric measurements, diagnose the pathology of the cervix, and identify Down syndrome in the unborn baby, if any.

Also at 13 weeks, the doctor will prescribe a biochemical test, if the woman did not do it at 10-12 weeks. When it is carried out, preventive measures are taken to maintain pregnancy.

Video of the thirteenth week of pregnancy

What happens to mom and baby at 13 weeks? This question worries many women during the period of bearing a child. In the article you will find only reliable information, as well as some tips that will help to bear and give birth to a healthy baby.

What's important at this stage

The thirteenth week for most women is the period of the end of toxicosis. The body gradually adapts to the changes that occur due to fluctuations in hormonal levels. In this regard, the girl's well-being is improving, which means she can fully enjoy her interesting position.

The first trimester is over, which means that the threat of involuntary termination of pregnancy has significantly decreased.

How long is 13 weeks?

The thirteenth obstetric is the 11th embryonic week. Accordingly, the thirteenth embryonic is 15 obstetric. The end of the 13th week is one month and 7 days.

Despite the fact that this period is marked by some relief of well-being, this does not mean that the expectant mother will not experience any inconvenience.

At the 13th week of pregnancy, a woman will have to face the following changes in her body:

Digestive disorders (constipation, diarrhea, heartburn, belching). With the growth of the uterus, there is pressure on the stomach and intestines, which entails an upset gastrointestinal tract. In addition, progesterone tends to relax the smooth muscles of the internal organs, which affects the peristalsis of the digestive system.
A growing tummy becomes the cause of a shift in the center of gravity, a change in gait. This often leads to leg pain and varicose veins. Compression underwear and phlebotonics help to cope with varicose veins.
Another unpleasant phenomenon is the increased tone of the uterus. This condition is expressed in pulling pains in the lower abdomen, as if it turns to stone. Usually, doctors prescribe rest and bed rest for such patients. In severe cases, drug treatment is necessary.
Drawing pains in the lower abdomen and in the lower back. Many pregnant women experience this symptom at 13 weeks. Discomfort is associated with a growing uterus and the effect of the hormone progesterone on the vertebrae. If the discomfort goes away at rest, don't worry. You should immediately consult a doctor in a situation where the pain is severe, accompanied by bloody discharge.
During the period of gestation, the mother's immune defense decreases. This is necessary to preserve the fetus. Against this background, nasal congestion and weakness may occur. Another common occurrence is thrush. In this case, there are white cheesy discharge with an unpleasant odor and itching in the genital area. Treatment of a fungal disease should be carried out under the supervision of a physician.

In addition to all the charms, at 13 weeks of pregnancy, many mothers experience a decrease or, conversely, an increase in blood pressure. In this case, the girl is faced with symptoms such as weakness, dizziness, headache, sometimes fainting occurs. This condition requires constant medical monitoring and the use of antihypertensive or hypertensive drugs.

Many drugs are prohibited during pregnancy. In this regard, self-medication is not allowed. A specialist should prescribe medications.

What Happens to the Body: External Changes

Thirteen weeks is the beginning of the second trimester. It is unlikely that a woman will be able not to notice external changes. First of all, this applies to a rounded tummy. Every day the fetus grows, respectively, the size of the uterus also increases. The lower abdomen becomes denser, the woman feels a hard lump. At this stage, you should take care of a comfortable wardrobe. Pants and jeans should not squeeze the belly. In addition, you need to give up high-heeled shoes, tight shoes. This is especially true for women suffering from edema and varicose veins.

At the 13th week of pregnancy, the mammary glands are noticeably enlarged. The woman no longer fits into her old bras. Now doctors recommend wearing comfortable underwear made from natural fabrics. You can use special maternity bras.

On the chest and in the tummy area, the expectant mother notices itching, stretch marks often appear. They are especially pronounced if there is a rapid weight gain. A light massage, a contrast shower and the use of special moisturizers will help prevent such changes on the part of the skin.

The size of the abdomen at 13 weeks depends on the constitution of the body of the pregnant woman and some other features. Often, a dark pigment line appears from the navel to the pubis. In girls with a predisposition to pigmentation, spots may appear on other parts of the body. There is no need to worry about this. Almost immediately after giving birth, these signs will disappear on their own.

And this is what tummies look like at 13 weeks of pregnancy

In obese mothers, the tummy at this time may look larger, which is associated with the presence of a fat layer.

The weight of your baby is now about 15-20 g, and the height is 7-9 cm. The size of a child can be compared to nectarine. On ultrasound, you can see a little man who no longer resembles an embryo at all. The head becomes more proportional to the body, the baby actively moves the arms, legs, bends and unbends the fingers, breathes in amniotic fluid.

Other changes:

bile is produced by the gallbladder;
the pancreas synthesizes insulin, which is necessary for normal glucose metabolism in the body;
during the waking period, the child constantly performs chaotic movements, training the muscular system;
the eyes, which were previously located on the sides of the head, gradually move closer to the bridge of the nose;
the formation of facial muscles continues, the laying of milk teeth ends;
the sucking reflex develops.

At 13 weeks, the heart works quickly and is capable of pumping 20 liters of blood per day. The heart rate is now 140-170 beats per minute.

The brain is actively developing, the rudiments of the first convolutions appear.

Dangers at 13 weeks of gestation

A young mother should be attentive to her health throughout the entire period. Now her body is very vulnerable, and she is responsible not only for herself, but also for the tiny life developing under her heart. Consider what complications may arise during this period.

Cold

During the period of childbearing, even a common cold can provoke many undesirable consequences. Diseases such as chickenpox and others are especially dangerous. Sometimes, against the background of an infection in the body, miscarriages occur or serious pathologies develop, due to which the doctor may even recommend terminating the pregnancy.

The treatment of acute respiratory viral infections, acute respiratory infections, influenza and other diseases is complicated by the fact that not all traditional drugs are allowed for a pregnant woman. If a high temperature rises, doctors prescribe paracetamol-based antipyretics, bed rest, and drinking plenty of fluids.

It is known that any disease is easier to prevent than to cure. The following recommendations will help a young mother not get sick:

dress for the weather, during periods of an epidemic, try not to visit crowded places;
saturate the diet with fresh vegetables and fruits, take vitamins;
when the first signs of a cold appear, you can resort to traditional methods of treatment (tea with lemon, bed rest, drinking plenty of fluids);
if a high temperature rises, it is better to call an ambulance. A specialist will help you choose drugs that are safe during pregnancy.

It should not be overlooked that at 13 weeks the temperature can be subfebrile. Basal temperature remains within 37 degrees. This temperature does not need to be brought down, because it is quite normal against the background of increased production of progesterone.

Painful sensations

Painful sensations of a moderate nature are a completely natural phenomenon during the period of bearing a baby, which should not cause anxiety to a woman. Basically, they arise due to the increased tone of the uterus. If the pain is quite severe and accompanied by other signs, you do not need to endure. In such a situation, it is better to see a doctor.

Pain can also occur of the following nature:

in the area of the lower extremities, which indicates a deficiency of some trace elements in the body, in particular, calcium;
headaches appear with high or low blood pressure;
in the lower back, discomfort may occur due to an increase in the abdomen;
due to indigestion, minor pain in the stomach or intestines may also develop.

A woman at 13 weeks should learn to distinguish acceptable physiological pain from pathological.

Pathological pain is usually intense and does not go away on its own. Signs such as vomiting, nausea, headache, high fever and others can join it. In this condition, a visit to a doctor should be immediate.

Allocations

Women who closely monitor their health know that normally the discharge should not have an unpleasant odor, their consistency is slimy, and the shade is transparent. Deviations from the norm almost always indicate the presence of one or another pathology:

Brown - indicates the presence of a small amount of blood in the secret, which is not the norm. They can appear after sex, a gynecological examination, but often this symptom also indicates more dangerous conditions, for example, the fading of pregnancy or an incipient miscarriage.
Yellow or grayish - may indicate a genital infection. In addition to a yellowish secretion with an unpleasant odor, a woman may feel itching and burning. When these signs appear, you should undergo a gynecological examination.
Light pink or beige - often appear in the presence of cervical erosion. If they are plentiful, you must inform your doctor.
Watery - appear when the amniotic fluid leaks. If you find this kind of discharge, it is important to consult a gynecologist. Leakage of water often occurs in such a dangerous condition as depressurization of the placenta.

Be that as it may, with the appearance of any pathological secretion from the vagina, you should not postpone a visit to the doctor. Excessive caution at 13 weeks gestation will not hurt.

The most dangerous sign while carrying a baby is vaginal bleeding. If bloody discharge appears, pulls the lower abdomen, feels sick, dizzy, pains and other alarming symptoms, you should immediately call an ambulance.

The following conditions can cause bleeding at 13 weeks:

placenta previa or its detachment;
the presence of a hematoma on the placenta;
low placentation;
injury to the cervix during a pelvic examination or during sex;
poor elasticity of blood vessels, which burst as the uterus grows.

To clarify the cause of the bleeding, mom needs to undergo an ultrasound scan and other examination methods. In the presence of a threat of termination of pregnancy, a woman is shown to be safer in a hospital setting.

Doctors judge the healthy development of a child taking into account the measurement of its parameters during an ultrasound examination. What do they look at ultrasound:

coccygeal-parietal size (CTE) - up to approximately 65 mm;
biparietal size (BPR) - from 18 to 25 mm;
the length of the nasal bone is from 2 to 4.3 mm;
fetal head circumference - approximately 70 to 95 mm;
collar space thickness (TVP) - no more than 3 mm;
the roundness of the belly of the fetus - from 60 to 80 mm;
femur - from 7 to 11.5 mm.

A baby's heartbeat in the thirteenth week of pregnancy should be between 140 and 170 beats per minute.

In the photo you can see what the baby looks like at 12-13 weeks after conception.

Twin pregnancy can be seen here

At this time, with the help of ultrasound, it is already possible to understand who is in the tummy, a boy or a girl. If a woman has gone through IVF (artificial insemination), pregnancy with twins or triplets is common.

It is not always possible to accurately determine the sex of the child. To do this, you can use 3D ultrasound or wait for a while.

What analyzes are carried out at this time

In addition to ultrasound, the first screening includes some other studies. This includes a general analysis of blood and urine, blood biochemistry, a study for TORCH infection, an analysis for Rh-conflict between parents. It is obligatory to pass tests for possible chromosomal abnormalities in the fetus. These include:

Study of the level of progesterone. This analysis helps to assess the development of the child at different times, to exclude a frozen pregnancy, to identify a delay in fetal development, to prevent miscarriage, and so on.
Analysis for hCG. Human chorionic gonadotropin is the so-called pregnancy hormone. By its amount in the blood, it is possible to control whether the child is developing normally. HCG begins to increase from the first days of conception tens of hundreds of times, and after 11-12 weeks it begins to gradually decrease. Read more about this harmonic.
Test for estradiol. Shows whether there is a threat of termination of pregnancy and in what state the placenta is.
Alpha-fetoprotein protein (PAPP-A). Another analysis that helps to identify some chromosomal pathologies (Down syndrome, Edwards and some others).

If a woman is over 35, she has a history of miscarriages and missed pregnancies, the family already has children with genetic abnormalities or marriage between blood relatives, tests for chromosomal abnormalities are mandatory.

Decryption of all data is carried out exclusively by a specialist. You should not try to establish a diagnosis yourself after receiving tests on your hands.

Can the fetus freeze at 13 weeks and why does this happen

The development of a child's life can stop at 13 weeks of gestation. This is due to many factors, among which are:

violation of hormone production;
chromosomal abnormalities in the fetus;
mother's transmission of infectious diseases;
abdominal trauma;
strong emotional stress;
abuse of bad habits;
diseases of the adrenal glands and thyroid gland;
inflammatory processes in the organs of the reproductive system.

To prevent miscarriage, a woman must be very careful about her health. It is forbidden during this period to lift weights, to engage in power sports. At 13 weeks, doctors recommend eliminating stress and physical injury. In addition, it is important to eat right, get more rest, and regularly undergo routine medical examinations.

It is quite difficult to survive the loss of a child, as evidenced by the reviews of many mothers. Relatives and the correct psychological attitude will help to cope with this condition.

Where is the uterus at this time

For mothers expecting a baby, the question often arises at the thirteenth week, where is the uterus during this period? At this stage, the child and the uterus itself are actively growing. The organ fills the hip part and rises higher, that is, into the abdominal region.

The height of the uterus is measured by the doctor at each scheduled examination. Normally, the height of the uterus is equal to the number of weeks of pregnancy. Therefore, at 13 weeks, it will have a height of 13 cm.

In the second trimester of bearing a baby, the organ becomes softer and more elastic, so the increased tone is no longer as terrible as in the early stages.

Nutrition for the expectant mother

At the 13th week of pregnancy, a woman should be careful about her diet. It often happens that at this time the mother still has no appetite. Despite this, you should never go hungry. The menu should contain fresh vegetables, fruits, cereals, dairy products, fish, natural juices. Be sure to include calcium-rich foods in your daily diet. These include broccoli, almonds, pumpkin seeds, cheese, cottage cheese, walnuts, and more.

You need to give up smoked meats, sausages, marinades, mayonnaise, ketchup, new exotic fruits, raw fish and meat. Nutritionists strongly discourage alcohol, soda, and caffeinated drinks during this period. Nutrition during pregnancy should be correct and balanced. This will help avoid too rapid weight gain and other unwanted problems.

Sexual intercourse at 13 weeks of gestation

Sexual relations between partners is a matter that must be resolved mutually. If there are no medical contraindications for this, such as the threat of termination of pregnancy, sexually transmitted diseases in partners and others, sex at 13 weeks is allowed.

Of course, during this period, the couple should not forget about caution, choose positions without deep penetration and pressure on the abdomen.

The beginning of the second trimester is already a third of the entire pregnancy. Surely, the woman has already managed to get acquainted with all the delights of this state. The following recommendations will help the expectant mother to bear and give birth to a healthy and strong baby, as well as maintain her good health:

Eat right and get plenty of rest. These seemingly simple tips are the foundation of a woman's and child's well-being.
Wear comfortable clothing and shoes. Avoid tight pants, tight sweaters, and high heels. During this period, the pregnant woman should feel as comfortable as possible, and beauty can be taken care of after childbirth.
It is better to postpone flights and long journeys. During this period, it is better to be in a familiar environment.
Your toddler is already hearing sounds. Listen to pleasant music, talk to him, try to avoid too noisy and crowded places.
Eat a lot of vitamins, strengthen the immune system. This will help you avoid catching a cold.
If you do get sick, do not hesitate to call a doctor. Self-medication in the thirteenth week of pregnancy is not allowed.

And, of course, try to tune in a positive way, because very soon you will meet with the long-awaited baby.

Video

All about the development of crumbs at 13 weeks of gestation can be found in this video.

The embryonic 13th week of pregnancy corresponds to the 15th obstetric week. The expectant mother and child overcome an important milestone - the end of the first trimester and the beginning of the second. By this time, doctors recommend registering with a consultation. From the thirteenth week, the pace of development in children may vary, including twins.

What happens to the expectant mother

The woman's body continues to prepare for feeding the baby. At the 13th week, colostrum, a liquid rich in nutrients for a baby in the first days of his life, can be excreted from the mammary glands. The increase in blood volume causes a slight expansion of the veins. Pigmentation appears on the body: the skin around the nipples darkens, and a strip from the navel to the pubis also appears. Many women are interested in where the child is at this time. The uterus becomes so large that its bottom rises, occupying not only the hip, but also the abdominal cavity. Due to the rounding of the abdomen at the 13th week, pregnancy becomes noticeable to others. The mother-to-be gains an average of 0.9–2.3 kg. At this stage, it becomes necessary to select clothes of a larger size and free cut.

What happens to the fetus

The size. At 13 weeks, the baby is like nectarine in size. The baby's height is 65–78 mm, weight varies within 14–25 g.

External development. What does a child look like? Outwardly, the fetus at 13 weeks resembles a little man. The body parts of the baby in the womb become more proportional than in the previous weeks of pregnancy. The kid actively moves, due to which his muscles are strengthened. Perturbations characteristic of periods of wakefulness remain erratic. At 13 weeks, the baby forms a face, acquiring the features with which he will be born, and the limbs are enlarged. When conducting an ultrasound, there is a possibility of determining the sex, since by this time the genitals of the fetus are developing. The child's skin remains transparent, blood vessels shine through it.

The development of internal organs. What happens to the heart at 13 weeks? It passes through itself more than 20 liters of blood per day. The gallbladder begins to perform its function. During this period of development, the pancreas already secretes insulin, the kidneys produce urine, and the intestines move from the umbilical cord to the abdominal cavity. The child begins to swallow amniotic fluid, distinguishing its taste. In addition, he performs 1-4 breathing movements per minute. The baby's vocal cords form in the womb.

Mom's nutrition

During pregnancy, a woman's body needs a full range of nutrients. The well-being of the expectant mother and the harmonious development of her child largely depend on the diet. At the 13th week, an increase in the calorie content of food is necessary. At this time, the need for microelements is growing: iron, selenium, zinc, potassium and calcium. The child forms its own supply at the expense of the mother's resource. Diet recommendations for this period may be as follows:

adherence to the diet. You need to eat 5-6 times a day. The diet should include meat, fish, vegetables, fruits, berries, dairy products and cereals. During pregnancy, it is useful to eat prunes and dried apricots, which contain fiber. It is possible to include natural sweets in the menu, such as marshmallows, halva, candied fruits. It is recommended to eat meat and fish in the morning. For dinner, dishes made from light dairy and plant-based products are perfect, for example, cottage cheese casseroles, stewed zucchini, broccoli, etc.;
gentle nutrition. During the cooking process, it is necessary to use methods such as boiling, stewing, baking and steaming. If a woman's nutrition was optimal before pregnancy, then with its onset a sharp change in preferences is not required. Servings are worth measuring. After eating, the expectant mother should have a slight feeling of hunger. In this way, overeating is excluded, the likelihood of difficulties with digestion and a set of extra pounds is reduced;
a sufficient volume of liquid. The daily intake of water for a pregnant woman is 2–2.5 liters. Natural drinking for the body has no contraindications and is not the cause of edema. In addition, it is useful to use homemade fruit drinks, juices and infusions;
removal of certain foods from the diet. Doctors usually recommend avoiding fried foods. In addition, you need to limit your salt intake. Its sufficient amount is found in vegetables and bread. Mayonnaise and sauces, sausages, canned food, coffee, chips, carbonated drinks, sweets should also be excluded from the diet.

Examinations and analyzes

Inspections. After registration with the consultation, scheduled gynecological examinations are carried out once a month. The doctor monitors the weight gain of the pregnant woman, measures blood pressure and pulse at each appointment. In addition, abdominal palpation is performed to determine the tone of the uterus. Internal examination is carried out at the first visit, during the remaining consultations - only according to indications.

Prenatal Screening. At the thirteenth week, a gynecologist may order the first ultrasound scan. Using this method, the vital signs of the fetus are assessed, physical defects in its development are identified or excluded. Ultrasound allows you to determine the thickness and transparency of the collar zone, the presence and size of the nasal bone, as well as listen to the heartbeat and track movements. In addition, this method will help to confirm pregnancy with twins. At 13 weeks. in addition to a general analysis of blood and urine, which are taken periodically up to each appointment of a gynecologist, a pregnant woman undergoes additional examination in order to exclude chromosomal abnormalities in the development of the fetus: Down and Edwards syndromes. Comprehensive diagnostics of this type includes an assessment of the correspondence of the hCG hormone and the plasma protein PAPP-A to the reference values.

Mom's health

The end of the first trimester is a favorable time for a pregnant woman. The symptoms that could have bothered her earlier (toxicosis and increased fatigue) are gone. Many women get used to their new position feeling emotionally uplifted. In most cases, the 13th week passes calmly, since by this time the risk of miscarriage is significantly reduced and the body adapts to changes in hormonal levels.

What difficulties are possible at the 13th week of pregnancy

However, during this period, the expectant mother needs to continue to closely monitor her health in order to competently act with symptoms such as:

the discomfort. What happens to the internal organs of a pregnant woman? Under the pressure of the enlarging uterus, they begin to displace. This leads to a temporary change in their functional characteristics. For example, the diameter of the rectum decreases, which causes constipation, and the sphincter between the esophagus and stomach is weakened. As a result, food in the digestive tract moves in the opposite direction. In this regard, women experience heartburn. In addition, with prolonged physical exertion, a feeling of heaviness in the limbs is possible. Proper nutrition, as well as adherence to a regimen of physical activity and rest, helps to cope with such symptoms;
pain. Expectant mothers may experience abdominal pain in the 13th week. One of the reasons for this is the increased gas production resulting from a decrease in intestinal motility. In addition, the pain may appear due to the stretching of the uterus and other muscles. Similar sensations for the same reason arise in the side. During the second trimester, women may experience frequent headaches. This is due to a change in vascular tone. These processes are considered natural companions of pregnancy. However, it is necessary to report such symptoms to a doctor who will recommend safe ways to eliminate them;
discharge. On the 13th week. their consistency and volume change. The discharge becomes thinner and more abundant. Moreover, they should not have a sharp unpleasant odor and a pronounced pathological color: green, yellow, brown or red. If these symptoms appear, you should immediately consult a doctor. The reason for the onset of such discharge may be a genital infection or the threat of termination of pregnancy. At the 13th week, the risk of candidiasis increases. It is accompanied by itching, burning, and cheesy white discharge. This disease occurs due to a weakened immune system and can return several times during pregnancy. Treatment is prescribed by a doctor depending on the degree of symptoms;
bleeding. As a rule, they arise in the event of a threat of spontaneous abortion, when the woman's body begins to reject the fetus. In addition, bleeding may indicate a miscarriage. If such a symptom appears, you need to call an ambulance.

Vitamins

If necessary, the doctor may prescribe the intake of various vitamins. Here are some examples.
Folic acid. At 13 weeks, the body still needs this element, which is responsible for the process of death of old cells and the appearance of new ones. Folic acid is involved in the formation of the placenta. How much of this substance can a doctor prescribe for consumption per day? The norm for pregnant women is 400 mcg.

B vitamins. It contains vitamins B6 and B12. They are responsible for the normalization of metabolic processes that occur between the organisms of the mother and the fetus, as well as for the full assimilation of nutrients by the child, the development of his nervous, cardiovascular, endocrine and immune systems. In addition, with the help of vitamin B12, the absorption of folic acid is improved. The daily intake of B6 is 2,100 mcg. Vitamin B12 is recommended to be consumed in an amount of 4 mcg per day.

Vitamin E. Tocopherol is used as an antioxidant. He participates in tissue respiration. How much vitamin E can a doctor prescribe to keep the expectant mother feeling well and to prevent muscle soreness while carrying a baby? The daily dose is 10,000 mcg.

Vitamin D3. Cholecalciferol is synthesized under the influence of ultraviolet radiation. This vitamin promotes the absorption of calcium and increases the protective functions of cell membranes. Natural sunlight is an important source of D3. Therefore, pregnant women are advised to be outdoors frequently. In addition, the lack of cholecalciferol is replenished with the help of vitamin complexes. The daily norm is 12-15 mcg.

Vitamin A. Retinol is involved in the overall development and nutrition of the baby in the womb, preventing low birth weight and anemia. The daily dose for pregnant women is 83 mcg.

Sport

At 13-13.5 weeks of gestation, moderate physical activity is an important factor in well-being and a cheerful mood. Sport contributes not only to strengthening the health of a woman during the period of bearing a child, but also helps her to look beautiful. The following options for classes are possible: yoga, pilates, aerobics, strength exercises. Before you start training, you need to consult with a gynecologist leading a pregnancy. In the absence of contraindications, it is recommended to follow several rules. The pulse should not exceed 130 beats per minute. Due to the growth of the abdomen and weight, women should wear stable shoes and comfortable clothing. Stop exercising if you feel fatigue or discharge.

This record was checked by a gynecologist-endocrinologist, mammologist, ultrasound specialist.

Child's age - 11th week (ten full), pregnancy - 13th obstetric week (twelve full).

A period of 13 obstetric weeks corresponds to 11 weeks from conception. If you count as normal months, then you are now in the third month, or the beginning of the fourth lunar month.

This is the quietest period in the life of the expectant mother and her baby.

Feelings in a woman in the 13th week of pregnancy

Like the previous ones, the thirteenth week brings mixed feelings to the woman. On the one hand, the sensations are pleasing and overwhelming with incredible anticipation, and on the other hand, you begin to understand that the carefree life has passed, and now you are constantly responsible for your baby, which makes it a little difficult to feel completely free.

The path to motherhood is filled with trials and excitement. It is especially hard for women who are expecting their first child. Thoughts are constantly spinning in my head: will there be enough strength and health to endure and give birth to a healthy child?

And then, as if for evil, all the acquaintances begin to talk about various complications that may arise during pregnancy and childbirth. Even a mentally balanced person, these stories cannot leave indifferent, and they often bring expectant mothers to tears and nervous breakdowns.

But still, the emotional state of the pregnant woman on this line becomes more stable and positive... This is due to the fact that she is less and less worried about the toxicosis of the first half. The manifestations of autonomic dysfunction, which influenced the stability of mood in the first three months, gradually disappear. The woman feels more comfortable and has an incredible burst of energy.

Quite often, women at this time are worried about:

Constipation, the cause of which is a violation of the peristaltic function of the intestine, which occurs against the background of hormonal changes. The uterus is constantly growing and leaves less and less space for the intestines, which is also the cause of constipation;
Convulsions in the calf muscles, which are most often manifested at night. The reason for this condition is a lack of calcium in the woman's body.
Hypotension(decrease in blood pressure), which can occur after the formation of the placental-uterine circle of blood circulation. Most often, a woman suffers this disease without obvious ailments. But if the pressure is greatly reduced, then it is better to resort to drug treatment. At a very low pressure, peripheral blood vessels contract, including in the uterus, which can cause insufficient blood supply to the fetus.
If on this line pressure rises, then, most likely, this is due to kidney disease, and not a predisposition to hypertension.

The tummy has rounded a little. Toxicosis is no longer worried. I expect a miracle.

What happens in a woman's body?

Your body has already produced enough hormones that are responsible for keeping the baby alive. Therefore, soon you will no longer be bothered by morning sickness. Worries about a possible miscarriage will leave you, and you will become less irritable;

The uterus is increasing in size, and now it is about 3 cm high and 10 cm wide... Gradually, it begins to rise into the abdominal cavity from the pelvic floor. There it will be located behind the anterior abdominal wall. Therefore, your relatives and friends may notice a slightly rounded tummy;

The uterus becomes more elastic and soft every day... Sometimes a woman notices a slight vaginal discharge that does not cause concern. But, if they have an unpleasant odor and a yellowish color - be sure to see a doctor;

You have probably already noticed that your breasts began to increase in size, this is because milk passages develop inside it. In the second trimester, with a light massage, a yellowish liquid, colostrum, can emerge from the nipples.

At 13 weeks, the 2nd hormonal screening is performed.

Fetal development at 13 weeks

For your unborn child, thirteenth week is very important. This is a key moment in shaping the relationship between mother and fetus..

The placenta ends its development, which is now fully responsible for the development of the fetus, producing the required amount of progesterone and estrogen. Now its thickness is about 16 mm. It passes through itself all the trace elements necessary for the child (fats, carbohydrates, proteins) and is an insurmountable barrier for many toxic substances.

Therefore, it is possible to treat the mother's disease, for which it is necessary to use medications (antibiotics). Also, the placenta protects the fetus from the effects of the mother's immune system, preventing the occurrence of Rh-conflict.

Your baby continues to form and develop all the systems necessary to ensure life:

Begins to develop rapidly brain... The child develops reflexes: the hands are clenched into fists, the lips curl, the fingers reach into the mouth, grimaces, shudders. Your baby spends some time actively, but still, while he sleeps more. It is possible to detect fetal movements only with the help of instruments;

Continues to actively form fetal skeletal system... The thyroid gland has already developed enough and now calcium is deposited in the bones. The bones of the limbs are lengthened, the first ribs are formed, the bones of the spine and skull begin to ossify. The baby's head is no longer pressed to the chest and the chin, brow ridges and the bridge of the nose can be clearly defined. The ears take their normal position. And the eyes begin to draw closer, but they are still closed by tightly fused eyelids;

Develops very gentle and delicate skin covering, there is practically no subcutaneous fatty tissue, so the skin is very red and wrinkled, and small blood vessels appear on its surface;

Respiratory system the baby is already quite well formed. The fetus is breathing, but the glottis is still tightly closed. His breathing movements train the muscles of the diaphragm and chest more. If the baby suffers from a lack of oxygen, then a small amount of amniotic fluid can enter the lungs. Therefore, if a pregnant woman is sick and there are pathogenic bacteria in the amniotic fluid, this can cause intrauterine infection;

At the end of the 13th week your baby's length will be about 10-12cm and the head has a diameter of approximately 2.97 cm. Its weight is now about 20-30 g.

At this time, the threat of miscarriage is significantly reduced, but there are still cases of spontaneous abortion. Therefore, the expectant mother should take care of her health, since the flu and even the common cold can harm your child.

Avoid strenuous physical activity;

Do not self-medicate;

In the autumn-winter period, use natural methods to prevent colds and flu: hardening, wash your hands after the street, do not visit crowded places;

Do not forget about proper nutrition: eat more fermented milk products, fresh vegetables and fruits. To avoid constipation, eat foods that have a laxative effect: prunes, beets, plums and bran. Do not get carried away with rice, pears and poppy seeds, they strengthen;

Spend more time outdoors, walk, communicate with people who are pleasant to you;

Do not use industrial cosmetics, rather use natural ones.

Wear compression hosiery in order to relieve heaviness and swelling in the legs, as well as to prevent varicose veins.

The most detailed pregnancy calendar by week

How did you feel on the 13th week? Share with us!

With the advent of the second trimester, cardinal changes begin to occur in the life of the expectant mother. Finally, the terrible toxicosis and irresistible drowsiness go away. However, this is all nothing, in comparison with the colossal work that the baby managed to do during this time. How the 13th week of pregnancy affects the development of the baby, and what changes can be expected in the near future, we will tell in today's material.

The second trimester of pregnancy is characterized by an improvement in the well-being of the mother.

During the entire pregnancy, the baby's heart did not stop for a second, it worked hard, passing through itself 23 liters of blood per day. In addition, at the thirteenth week, the baby has milk teeth.

His victories do not end there. In the formation of a full-fledged digestive system. The intestine is becoming a real springboard for the formation of connective tissues, focused on food processing. The pancreas starts producing insulin.

It is at the thirteenth week that the child's vocal apparatus is finally formed, and all the muscles accompanying this process. This period is of tremendous importance for gender differentiation. Simply put, the baby "decides" who he will be a boy or a girl.

Depending on one or another sex characteristic, the development of internal and external genital organs occurs. At this stage, depending on gender, the production of sex cells occurs and the prostate gland begins to form.

By far the most exciting part of pregnancy is identifying a baby. At the thirteenth week, this is already possible, but only if the child has taken a comfortable position. Ultrasound specialists are more likely to be able to identify the boy.

In the case of girls, incidents often occur. This is due to the fact that at the thirteenth week, the primary sexual characteristics of girls are not yet fully formed, and to some extent may resemble a penis. You can be convinced of your assumptions only on the following diagnostics.

Looking at the ultrasound scan taken at the thirteenth week, we can say with a high degree of probability that the baby's face has already acquired expressiveness and clarity. Eyes, mouth and nose can be clearly seen.

Compared to the last visit to the diagnostician, the baby has grown considerably stronger and more mature. At the thirteenth week of pregnancy, the size of the fetus is about 7-8 centimeters, the weight can fluctuate between 15-25 grams.

The rapid development of the baby took place not only physiologically, but also emotionally. At this time, the baby already actively learns the world around him, reacts to sounds coming from the external environment, clearly distinguishes between dark and light colors, and also responds to any interactions with the stomach, be it stroking or talking.

By this time, the child had already mastered minimal facial expressions, developed sucking and swallowing instincts and learned to yawn very funny. At this time, the baby sleeps very little, his sleep is short and intermittent. To rest, it is enough for him to sleep only a few minutes.

For most of the day, the child is awake. It is also worth noting that the chaotic and disordered movements of the fetus are a thing of the past. Now the baby is moving purposefully and consciously.

The child can already appreciate how warm and good he is in his mother's tummy. The fact that he is pleased can be judged by the smile that sometimes appears on his face.

At the thirteenth week, the baby develops tastes in food. He simply adores some products, he categorically rejects others, which he notifies his mother with an overwhelming feeling of nausea. At this very time, it becomes clear that the child is finally prepared for full communication with his mother. Now he is able to distinguish between songs, mother's gentle voice and many other sounds.

Your baby is like ...

At the thirteenth week of pregnancy, the child's height is 65-78 millimeters, its weight varies between 14-20 grams. The size of the fruit resembles nectarine.

Meanwhile, the rapid development of the child does not stop for a single second. The fetus no longer resembles an embryo; rather, it is a fully formed little man. The baby's head began to take on its usual size, it is not as big as that of the embryo. From now on, all parts of the crumbs' body are fully proportional to each other.

Your baby is about this size at 13 weeks

Consider the most important changes in the life of the fetus that occur in the thirteenth week of pregnancy:

the gallbladder is fully formed, which begins to perform its primary task - the production of bile. With the help of the pancreas, the production of vital insulin begins. It is he who is responsible for the processing of glucose in the baby's body;
the child begins to actively move, thereby strengthening the barely formed muscles. Most of the baby's movements occur during his waking period;
the face of the crumb is already completely formed. It acquired the features with which he was lucky to be born into the world. The eyes, which until this moment were located in the lateral parts of the skull, have already managed to move to their usual place. The baby is actively developing a sucking reflex, a primary set of mimic reactions is formed and milk teeth are formed;
the heart continues to actively develop, and gain more and more momentum. In a day, it is capable of passing more than 20 liters of blood through itself;
processes associated with the activation of brain activity are triggered in the baby's head. In place of small grooves, cerebral convolutions begin to form.

Sex is not yet clear

13 week of pregnancy: key changes in the body of the expectant mother

With the advent of the second trimester, the best time begins in the life of a pregnant woman. Toxicosis is in the distant past, hormones have finally calmed down, and you can safely enjoy this wonderful time.

The body of the expectant mother has successfully coped with one of the most difficult tasks - it has adapted to the fetus that develops in it. However, this does not mean at all that mommy just needs to sit down with folded hands.

The time has come when you need to seriously think about health problems: to prevent constipation, minimize swelling, and reduce the risk of stretch marks.

Obviously, external changes are also inevitable. The outlines of the waist are gradually blurred, and a rounded tummy appears in their place. By the way, the thirteenth week is the best time to go shopping for clothes. Particular attention should be paid to the correct choice of underwear, on which the further course of pregnancy depends.

Special creams help with stretch marks

The bra should ideally match the size and comfortably support the breast, which by this time has already managed to noticeably increase in volume. Better to give preference to bodices with wide straps. During this time, the breast of the pregnant woman continues to enlarge.

As practice shows, during pregnancy, the usual breast size of the expectant mother can increase by 2-3, or even 4 times.

How does the uterus change at the thirteenth week of pregnancy?

By the time the thirteenth week arrives, the uterus continues to slowly but surely increase in volume. Over time, it fills the entire hip part, and begins to rise to the abdominal cavity.

Of course, the organs that are the "legitimate owners" of this part of the body do not like this neighborhood, and they begin to actively declare their dissatisfaction. As a result, a pregnant woman has to experience various consequences of such internal confrontation, manifested in the form of heartburn or excessive shortness of breath.

The uterus is already perfectly palpable. At each examination, the attending physician records its height. Its standard value corresponds to the number of weeks. Accordingly, at the thirteenth week, the height of the uterus of a pregnant woman should reach the cherished 13 centimeters.

Moreover, its width is about 10 centimeters. At this time, the uterus becomes softer and more elastic, so there is no need to be afraid of the resulting tone. In a normal state, the uterus continues to contract, but only a small number of times.

At 13 weeks, the uterus begins to rise and is already palpable

Tummy in the thirteenth week of pregnancy

In miniature mothers at this time, the belly is just beginning to show through, while in everyone else, the baby is already beginning to proudly declare itself with a protruding maternal belly, which is difficult to hide under loose clothing. Mom still needs to stay alert and watch her body.

At this time, a slight uterine tone may occur, the effect of which can be minimized by lying down for 15-20 minutes. Then the muscles will relax, and it will become much easier.

If such situations become more frequent, it is necessary to urgently contact your attending gynecologist.

As a rule, in such cases, drugs cannot be dispensed with. Most gynecologists prescribe rectal suppositories, which will help to significantly reduce uterine tone, and do not pose any harm to the health of the mother and her baby.

At the same time, most women prefer to do without medication support. It is very easy to avoid problems with increased uterine tone. It is enough to give up high heels and uncomfortable shoes, not to carry heavy bags and not to worry.

Abdominal pain is an urgent reason to see a gynecologist

In addition, a pregnant woman may experience severe intestinal discomfort, which in most cases is associated with an excessive build-up of gas.

In order to minimize such negative consequences, it is necessary to find out which product the body reacts to in this way, and temporarily exclude it from the diet.

Pain in the thirteenth week of pregnancy

Most pregnant women who have crossed the thirteen week mark complain of pain on the sides of the abdomen. This discomfort is quite natural. This is due to significant stretching of the muscles, the main task of which is to hold the uterus. Such unpleasant sensations are not capable of harming the mother and her baby.

If the expectant mother suffers from seizures, which literally cramp the calves, this is a clear indicator that there is an acute lack of calcium in the body. In most cases, these seizures occur in the evening or at night. Reducing the risk of such unpleasant pain sensations is quite simple.

It is necessary to revise your usual diet and increase the amount of plant calcium consumed. You should not get carried away with fermented milk products with an excessive calcium content, otherwise the baby may have serious problems with ossification of the fontanelle, and this, in turn, leads to a complication of the child's patency through the birth canal.

Seizures are due to calcium deficiency

Viral diseases in the thirteenth week of pregnancy

Unfortunately, the expectant mother is very susceptible to flu and other viral infections. In order to avoid negative consequences, it is better to avoid crowded places, especially during an aggravation of various viruses.

Fortunately, at the thirteenth week, an ordinary viral infection is no longer as dangerous as in the initial stages of the "interesting situation", but it is better to be safe in order to avoid complications.

The consequences of an aggravated form of the course of influenza can lead to the appearance of congenital abnormalities and even premature birth. In any case, the prevention and treatment of a viral infection should be timely and symptomatic.

Only a qualified specialist can give an accurate recommendation on which medications to use in order to reduce the risk of any complications.

Temperature rise in the thirteenth week

It often happens that, against the background of a cold, the expectant mother's temperature rises sharply. Gynecologists urge women not to panic in this case, and not to try to knock her down in all possible ways.

A drug with an antipyretic effect is allowed to be taken only if the thermometer shows more than 38 degrees, during the last few days. It is better to withstand high temperatures with the help of drugs that include paracetamol.

Plus, for the thirteenth week, a temperature of 37-37.5C is the norm. And, if the expectant mother feels fine, then there is no need to take any measures to "bring down" the temperature. You can start to worry only when the elevated temperature is accompanied by any secretions.

Colds at 13 weeks are not as scary as in the early stages, but they also require a doctor's consultation

Discharge in the thirteenth week

During this period of pregnancy, the appearance and composition of the usual discharge may change. From now on, they have acquired a more liquid form, and there are more of them. Don't worry, it's natural.

It is imperative that the discharge is free of any color or odor. You need to urgently seek help from a doctor only if, at some point, the discharge has dramatically changed its color and texture. For example, from transparent ones they turned gray, brown or bloody.

Pain and irritation in the genital area is a clear sign of the development of a dangerous infection, which is strictly forbidden to be treated at home. The only way out of this situation is an urgent visit to the doctor. Otherwise, this situation is fraught with spontaneous miscarriage.

Bleeding in the thirteenth week of pregnancy

Although many pregnant women think that bleeding is tantamount to miscarriage, in fact, in some cases it is not dangerous. The first thing to do is to establish the cause of the bleeding. Such consequences can lead to:

detachment of the placenta;
the presence of internal hematomas resulting from a fall;
injury to the cervix, which could be obtained as a result of a non-professional examination by a gynecologist or sexual intercourse;
erosion;
low level of capillary elasticity. Due to the fact that by the thirteenth week the size of the uterus is already quite large, the capillaries simply may not develop elasticity. As a result, they burst under strong pressure.

Not all causes of bleeding can lead to a pregnancy failure. However, this does not mean that you need to postpone the visit to the doctor. It is better to go through the ultrasound diagnostic procedure once again.

Ultrasound at the thirteenth week of pregnancy

The first routine ultrasound diagnostics is performed for a period of 12-13 weeks. It is at this moment that the expectant mother first meets her baby. At the thirteenth week, you can already see how the small heart pulsates, how the legs and arms move.

In the process of diagnosis, the doctor determines the exact duration of pregnancy, the number of embryos, assesses the fetus for compliance with the standard values, assesses the risk of intrauterine defects.

Only a doctor will fully assess the condition of the fetus and mother.

As a rule, at the thirteenth week, the expectant mother is sent for the first screening test, which will determine the risk of various pathologies associated with the development of chromosomes (for example, Down's syndrome).

In the course of a detailed diagnosis, the doctor, with particular care and scrupulousness, must assess the thickness and transparency of the collar zone of the fetus, examine the nasal bone, confirm or deny the presence of other physiological defects.

With the help of biochemical screening, you can determine the ratio of hormones to protein in the body of a pregnant woman. Based on all the laboratory tests carried out, the specialist makes a conclusion about the possibility of a healthy baby being born, without any pathologies.

Mothers whose test showed a value of 1k 350 and below are at risk. However, this does not mean that the baby is guaranteed to be born sick. A screening test only indicates a high risk of a chromosomal abnormality. The probability of giving birth to a healthy baby always remains.

Based on the results of screening, it is possible to judge the normal course of pregnancy or the presence of problems with the development of the baby (inhibition of growth, malformations of internal organs, problems with the number of chromosomes).

Daily diet at thirteenth week

A wide selection of vitamins and minerals is the main condition for the nutrition of the expectant mother. You should not single out any one useful microparticle. The growing body of the baby needs proteins, fats and carbohydrates in equal proportions.

All products that are eaten by a pregnant woman must undergo a minimum level of heat treatment, that is, they must be boiled or steamed. Various types of lean meats, vegetables, legumes and fruits with a minimum glucose content should regularly appear on the plate of the expectant mother.

In order to reduce the risk of occurrence, any meal can be supplemented with a glass of tomato juice or freshly mashed vegetables and fruits. Particular attention should also be paid to plant-based calcium, which is found in persimmons, kiwi and lentils.

Sexual life in the thirteenth week of pregnancy

Undergoing a series of chemical reactions, the libido of a pregnant woman can increase several times. However, sexual relations during this period of time can lead to serious consequences, ranging from psychological and physiological discomfort and ending with the risk of spontaneous pregnancy failure.

At the same time, at the thirteenth week, a woman's erogenous zones are especially aggravated, which has a positive effect on the quality and duration of sexual intercourse. Nevertheless, if a woman feels obvious discomfort, it is better to refuse intimacy.

The diet should be fruits, vegetables, different types of meat and fish.

Alcohol and smoking during pregnancy

Alcohol is categorically harmful to the developing fetus. This is due to the fact that alcohol can easily overcome the placental barrier, thereby exerting a negative impact on the formation of the child.

It is at this time that the formation of the most important organs and systems of vital activity takes place in the baby, which can be disturbed by one glass of wine. So before drinking, a pregnant woman should think about what is more important to her: a one-time pleasure or the presence of serious health problems in the baby.

Smoking is also unacceptable for the expectant mother. In the case of heavy smokers who cannot imagine their life without a cigarette, you can resort to special patches and less harmful substitutes. Of course, they should be selected by the attending physician.

Sitting on the couch before childbirth will only aggravate the mother's health - physical activity is necessary

Physical activity

An active life is the key to a properly proceeding pregnancy. She is especially welcome at the turn between the first and second trimesters, when the body of the expectant mother has already fully adapted to the baby.

At the thirteenth week, a woman begins to experience a new surge of strength and energy. This is the best time to do sports. You can go to the pool or go to yoga (it is better if it is a specialized group focused on expectant mothers).

You can do a special set of exercises at home. However, only if approved by the attending physician. In this case, it is absolutely not important what and how a pregnant woman does, the main thing is that she does not stop moving.

Adequate rest, nutrition, a healthy lifestyle - three components of a happy pregnancy

Necessary examinations and examinations

Most likely, the woman has already registered with the antenatal clinic, so she visits the doctor only once a month. At this time, an ultrasound scan can be performed in order to exclude developmental pathologies. At 13 weeks of pregnancy, it is still possible to terminate the pregnancy if a developmental abnormality is detected.

Another reason for an ultrasound scan at 13 weeks is to determine the gestational age of the fetus. The margin of error is reduced to only two days. This is important, since some women, for various reasons, cannot give the exact date of the last menstruation.

An ultrasound scan is performed using a vaginal probe. The head, limbs, beating heart are already visible on the screen. It is very difficult to determine gender at this time. On the second ultrasound, the gender of the baby will be known for sure.

Pregnancy is not a reason to give up your usual activities, be it sports, travel or photo sessions

Recommendations regarding the lifestyle of the expectant mother:

Since the tummy is already quite noticeable, it is better to refuse too tight clothing styles. Loose clothes of a simple cut will look most optimal. It is better to choose trousers with a special elastic insert.
At the thirteenth week, the baby is already able to feel the mood of the mother, he passes all her joys and disappointments through himself. In this regard, it is necessary to minimize various experiences and stresses. You need to try to surround yourself with beautiful things, cultured and well-mannered people, listen to light melodic music. You can sing lullabies to your baby, then after birth, he will be more willing to fall asleep to the enchanting sounds of his mother's voice.
At the beginning of the second trimester, you can begin to actively attend all kinds of classes for expectant mothers. In such courses, they teach correct breathing during labor, and talk in detail about the peculiarities of the course of pregnancy. This information will help you get through labor easier.
If a couple wanted to go somewhere on vacation before the baby arrived, then there is no better time than the beginning of the second trimester. However, the trip can take place only in the absence of various pathologies in the development of the fetus, and with the permission of the attending physician. Such a trip will help to distract from endless tests and visits to doctors.
In order to protect your baby as much as possible, it is categorically impossible to take any medications without the consent of a gynecologist. This is due to the fact that even the most harmless drugs can cause serious harm to the health of a still fragile baby.
For the normal development of the child and the comfort of the expectant mother, a calm and proper sleep is extremely important. Particular attention should be paid to the sleeping place of a pregnant woman. It should be as comfortable and convenient as possible. Better to use special bedding for expectant mothers.
