Development of the fetus for weeks of pregnancy, sensations of the mother and a description from the photo from the beginning of conception of the child to the birth

Pregnancy by week, fetal development in the womb of a woman

Birth processand the development of a new person's life in the womb brings tremendous transformations in the woman's body that she inevitably feels. Everything changes - the shape of the female body, the sensations, the awareness of the surrounding and inner world. It turns out that the future mother develops with her child. I wonder what the woman feels during pregnancy?

We will consider the development of the fetus for weeks of pregnancy today, what exactly happens every week of pregnancy, how the height and weight of the fetus change, what new sensations arise in the future mother as the pregnancy period increases.

You will learn when a tiny toddler begins to hear my mother's speech, when you can take a photo on the ultrasound of the fetus and much more.

The entire pregnancy period normally lasts 10 obstetric months( or lunar months), in each of which for 28 days, or 40 weeks - 9 normal calendar months.

First week of pregnancy, how does the fetus develop?

Under the first week for obstetric terms, it is considered the last day of menstruation. During this period, conception does not necessarily occur, it can happen in 2 or 3 weeks, depending on the time of ovulation.

To find out about the onset of a long-awaited condition, it is possible only from baseline temperature measurements. At this time, home tests whether the delivery of blood to HCG does not show the true result. There are no obvious signs, the woman is still active, only preparatory stages are in the body.

It is interesting that at the time of the appearance of the embryo, the gestation period is already 2 or even 3 weeks. Why is that? Let's define, from what we will consider the term.

There are concepts of embryonic and obstetric term. The embryonic period of pregnancy is the true period from the moment of conception. The obstetric period is from the first day of the last menstruation. The obstetric period is on average 2 weeks longer than the embryonic period.

During ultrasound, in the card of a pregnant woman, the hospital sheet will always indicate the obstetric period by the date of the last menstruation. And here from the third week of pregnancy and the development of the fetus begins. Below you will find a description of each week of pregnancy: how the

develops a fetus, what happens to the uterus, how the sensations of a future mother change.

Fertilization is the fusion of an egg and a sperm in the fallopian tube. As soon as fertilization has occurred, one main cell is formed - a zygote. It is the basis of all the systems and bodies that will be laid, and formed over the course of 9 months. The first violent chemical reactions begin, the intensified synthesis of specific hormones of hCG is observed on the 5th-6th day. This will reduce the immune defense of the mother's body, to preserve the embryo.

Recommendations for a future mother here will be:

• will get rid of bad habits, smoking, alcohol;
• begin to eat properly, the body must receive proteins, fats and carbohydrates in a ratio of 1: 1: 4, respectively;
• to avoid medical procedures associated with irradiation, when taking medications, consult a doctor;
• may require multivitamins that include folic acid, a future mother to begin the course is desirable even at the stage of planning preparation.

Sensations of a woman do not differ, she leads a habitual way of life, physiological changes will come a little later. But some, moms, with very developed intuition and sensitivity, can determine the exact onset of conception without tests and tests.

2nd week of pregnancy

For obstetric dates this is the time of ovulation. In this period after the end of menstruation, the body is actively preparing for reproductive function. The ovum produces an ovum, in the presence of several, a multiple pregnancy may occur. Through the abdominal cavity goes to the fallopian tube, the whole process is controlled by the hypothalamus.

Egg during the day awaits the onset of conception. Spermatozoon has a higher viability up to 5 days.

The time of ovulation falls on the middle of the cycle, if it consists of 28 days, it means - on the 14th day the egg matures. If conception does not happen, then in 2 weeks the unfertilized female cell is excreted during the menstrual period.

Sensations of a woman:

• changes hormonal background, there may be a sensitivity to smells;
• pulling sensations in the lower abdomen;
• increased libido, the development of sensuality and sexuality.

Calculate the moment of ovulation is possible by special pharmacy tests, or by baseline temperature measurements!

These are optional symptoms, more often a woman does not notice such subtle processes that adjust her body to maternity.

3rd week of pregnancy

At the end of the second and beginning of the third week( on average, on the 14th day of the cycle), ovulation occurs. At this point, the ovum of the woman leaves the ovary in the fallopian tube and where it meets the spermatozoon in the next day. Of the 75-900 million spermatozoa that fall into the vagina, the cervical canal is less than a thousand. And only one, the fastest and strongest, will penetrate into the egg.

In fact, this is the first week of the birth of a future life. Conception is as follows.

The sperm and egg carry a half-set of chromosomes of the future person. As a result of their fusion, the first cell of a new organism with a full chromosome set - the zygote - is formed.

Chromosomes determine the sex of the baby, the color of his eyes, and even the character. Zygote begins to divide and move to the uterine cavity. The path to the uterus will take about 5 days, by this age the embryo will consist of approximately 100 cells. The next stage - implantation - embryo introduction into the uterus wall.

Implantation of the embryo can be accompanied by scanty smearing discharge, sometimes a woman simply does not notice them.

Sensations of a woman depend on her sensitivity. Some people experience nausea, weakness, dizziness. The most important thing at this stage is to ensure sufficient intake of protein, folic acid, calcium and iron into the body. Therefore, it is necessary to regulate nutrition and the regime of the day, overwork and stress can be detrimental to the course of development.

4 week of pregnancy

During this period, the placenta and amniotic fluid begin to form, they will provide vital activity to the crumbs. In addition, the head appears, and three main layers are laid, after which systems and organs will develop. Responsible for their formation of paternal genes.

Appearance of the embryo:

• ectoderm - formation of the brain;
• endoderm - organs of the gastrointestinal tract, thyroid, liver;
• mesoderm - musculoskeletal and circulatory system.

A ball of cells is officially called an embryo. The size of the fruit at this time is like a poppy seed, about 1.5 mm.

At the end of this week, the expectant mother notices that the expected menstruation does not begin. At this time, a woman can feel drowsiness, weakness, increased sensitivity of the mammary glands, mood swings. A pregnancy test shows a positive result. The test determines the hormone hCG, which begins to be produced after implantation.

The embryonic period lasts up to 12 weeks. There is a bookmark of the axial organs and tissues of the baby. A yolk sac with a reserve of nutrients, an amniotic bladder, is formed from these extra-embryonic organs subsequently develop fetal membranes and a chorion, the future placenta. Below we will analyze what happens in the embryonic period in each week, how the height and weight of the fetus change and what sensations await a woman.

Sensations of the mother:

• there is a sharp change of mood, drowsiness or vice versa - a surge of energy;
• increased irritability to smells, tastes;
• nausea in the morning, dizziness;
• can already increase the chest, the sensitivity of the nipples will increase.

To determine the pregnancy is obtained using a test or ultrasound. During this period it is necessary to provide a full-fledged food, sparing regime. It is important to take care of immunity, avoid visiting mass events, and contact with patients.

5-th week

Future mother is already beginning to suspect a new condition, because menstruation should have happened a week ago. In addition to psychoemotional moments, there are other signs of conception.

Physiological changes in a woman:

• increases the amount of secretions, normally they resemble slime, like chicken protein, at this time, a plug is formed that protects the fetus before delivery from infection;
• severity and pain in the abdomen can signal the development of a threat, or be part of a natural process, in any case, a gynecologist's consultation is necessary;
• fainting and dizziness speak of sudden sugar races, so the whole day diet should be divided into small portions, increasing the number of receptions;
• emotionally observed instability, there are fears, doubts, unrest for the assigned responsibility.

The baby reaches a size of 1.7-2 cm, a large head and a small body give a similarity to a tadpole. This is a very important period, because the spinal cord and brain are being laid. A small heart beats and circulates the blood. For the mother at this time it is important to continue taking folic acid for the normal development of the nervous system, to ensure a full sleep and rest.

The embryo consists of three layers:

1. of the outer ectoderm, from which the ears, eyes, inner ear, connective tissue form;
2. endoderm, from which the intestines, bladder and lungs will develop;
3. mesoderm - the basis for the cardiovascular system, bones, muscles, kidneys, reproductive organs.

The fetus is defined by the anterior and posterior poles - the future head and legs. The body of the embryo is laid along the axis of symmetry - the chord. All organs will be symmetrical. Some are paired, for example, kidneys. Others grow from symmetrical buds, for example, the heart and liver.

At the 5th week of pregnancy at a hCG level of 500-1000 IU / l, it is possible to determine a fetal egg with a size of 2 mm, this is the size of a sesame seed. Every woman experiences this period differently, but most of them have nausea, drowsiness, intolerance of smells - signs of toxicosis.

6 week

Now the baby is no more than lentils, at the beginning of the week 3 mm, and by the end - 6-7 mm. The embryo is something like a small fish and while little resembles a person. There are rudiments of hands and feet. When the brushes appear, the legs will still be in the form of rudiments. The hemispheres of the brain are formed. A small heart pulsates, it divides into departments.

The future placenta is laid out from the villus of the chorion, the blood vessels are actively growing, through which blood is exchanged, and, accordingly, everything necessary for the future child between mother and baby.

At this time, the phenomenon of toxicosis may increase, may develop severe weakness and vomiting. Important in these weeks of pregnancy is a sufficient amount of drinking.

This week, you can use ultrasound to measure KTP( coccyx-parietal size), its norm of 5-6 mm indicates a proper development. In addition, the pictures will look at the bumps of pens and legs, the bookmarking of the fingers begins, they will soon become full-fledged limbs. And while the formation of the mouth, chin, cheeks.

Changes in the future mother:

• hormonal changes begin to affect eating habits, hunger is constantly felt, or vice versa, the products cause nausea;
• set of weight does not yet occur, if there is a toxicosis, a woman can even lose weight;
• if the discharge changes, accompanied by a specific odor and discomfort, you need to urgently consult a doctor, the risk of fungal diseases is high;
• can increase the area in the lower abdomen, which is easy to detect by clothing, the lack of muscle tone of the uterus gives such an effect.

A woman should avoid any contact with chemicals, detergents, or tobacco smoke. Do not go to baths, beaches, solariums, swimming pools.

7 week

Embryo approximately with blueberry, growth 8-11 mm, weight up to 1 g. There are hints of a future nose, eyes, ears and mouth. There is a fantastic speed of brain growth - 100,000 cells per minute! Interval finger gaps have already appeared on the handles, but fingers are not yet divided. The umbilical cord and the system of uteroplacental circulation are formed: the breathing and nutrition of the baby comes from the maternal blood.

It is at this time that many future mothers often come to the first ultrasound in pregnancy. At 7-8 weeks with KTP( coccyx-parietal size) 10-15 mm. On ultrasound, palpitation is determined with a frequency of 100 to 190 beats per minute, which is significantly more than in an adult. At this time, the first photo of the fetal development gallery is taken weekly. Without instructions from the doctor and do not understand where to look. Later it will be more visible, especially on a three-dimensional ultrasound.

Still mum does not notice an increase in the abdomen, and the gynecologist can already say about the increase in the uterus. The woman shows an increase in urination, which is associated with an increase in the volume of fluid in the body.

The main feature of this period in the fetus is the replacement of the yellow body of the placenta, which by this time must be fully formed and fulfill its nutritional and protective functions. The risk is present if previously transmitted infections have led to anomalies.

Fetal development for weeks of pregnancy Description with photo:

• grows by leaps and bounds, reaching a size of 1.8 cm and weight of 2 g;
• already formed both hemispheres of the brain, the construction of the nervous system continues;
• trunk is exactly the size of the head, there is also a small tail on the coccyx;
• completely regulates blood circulation, the placenta now supplies oxygen, nutrients, protects against toxins, infections, pathogenic microflora;
• continues to form the musculoskeletal system, fingers are distinguishable, the tissues of the skeleton are transformed into bone tissue, the embryo can bend the elbows of the knees;
• heart already consists of 4 chambers, distills blood through a small body;
• on the face appears nose, with nostrils, also the upper lip, the auditory system is formed, in the mouth the rudiments of the teeth are laid;
• covers already consist of 2 layers, the upper one - the epidermis;
• by the end of the seventh week appears between the limbs of the mound, a little later you can determine who it is - a boy or a girl.

The future mother is already beginning to feel all the complications of pregnancy. To the toxicosis, nausea and drowsiness can join puffiness, frequent urination, gas formation and disturbances in the digestive system. The baby develops very quickly, respectively, the uterus reaches the size of an orange, which is accompanied by heaviness and pressure in the lower abdomen. Areola nipples darken, a line is drawn down the abdomen to the navel.

8 week

A kid the size of a string bean, from 15 to 40 mm, and weighing about 5 grams. Over the past two weeks, he has grown 4 times! The contours of the face continue to develop, they become more elegant, the upper lip, the tip of the nose, the formation of the eyelids begin.

At the 8th week of pregnancy ossification of bones begins - hands, feet, skull. The structuring of the gastrointestinal tract, heart, kidneys, and urinary bladder is completed.

Somewhere on 7-8 weeks of pregnancy the baby starts to move, but these movements mom will not feel in the coming months.

The Kid continues to grow. Almost all systems are laid, further development continues. The tail disappears, the ability to move chaotically with handles, legs, it unclenches fingers. Bones and joints become stronger every day.

The visual system is formed, the embryo becomes less outwardly like an alien, the eyes are closer to each other. On ultrasound, you can consider the ear canal, the face has a more defined contour with a barely noticeable facial expression. At this time, the baby can already react to the touch.

Here the main symptoms of pregnancy begin to be clearly manifested, according to which women who do not attach importance to their condition and, forgetting about the delay, can already accurately guess their interesting situation.

Key features:

• is markedly rounded silhouette of a woman, in the abdomen, chest, hips, gait becomes smooth, measured;
• will change the skin condition, for the better or worse depends on the individual characteristics, or appear rashes and redness, or vice versa - the face will be clean, fresh, without a single speck;
• taste preferences are quite original, the desire to eat something not by season occurs very often, or the pregnant woman becomes selective in food, stopping just a few products.

Week 9

This period characterizes the intensive growth and transition from the embryo to the fetus. The head is still large enough and lies on the chest, the arms and legs are well formed. The kid can move around the amniotic fluid until his small size( with a grape) allows. Genital organs are indicated, but ultrasound can not be determined yet, you need to take a blood test.

A small human fetus at this stage is only about the size of a grapes - its length is 35-45 mm, and its weight reaches 10 g. There is a laying of the reproductive system, and the adrenal glands are already producing hormones, including adrenaline.

Intensively develops the brain, including the cerebellum, which is responsible for the coordination of movements. Movements become more controllable. The digestive system is actively developing. The liver begins to produce new blood cells. The head occupies half of the entire length of the body. Tiny fingers become longer.

The amount of circulating DNA of the embryo in the mother's blood is sufficient to conduct a non-invasive perinatal test to determine the sex of the child.

Signs of toxemia in my mother still persist. Usually at this time she turns to the gynecologist to stand on the register.

It is important for a woman to continue to monitor her health, when bloody, yellow, green secretions appear, you need to see a doctor. Also, the pain in the lower back and lower abdomen should be alerted. The doctor can recommend a genetic counseling, if necessary, take a biopsy of the chorion to identify developmental anomalies.

Fresh and high-quality products should predominate in the diet. If you suffer from heartburn, avoid sharp spicy dishes. Soften the toxicosis of rose hips and green tea without sugar.

10 week

There comes a more peaceful period, the expectant mother gets used to a new condition, and the baby has already formed systems and organs, the development of the brain continues. Its weight is close to 7 g., The head gradually begins to rise from the chest.

The most amazing thing at this time is brain development. The process takes place with incredible speed, every minute new chains of neurons are formed. In the brain, 250,000 neurons are formed every minute.

Fingers continue to lengthen, but the membranes remain between them. The main organs - liver, kidneys, lungs, intestines, are located correctly, continue to improve. The kidneys begin to work, fulfilling their main function - urine production. Between the abdominal and thoracic cavities a diaphragm is formed. The synthesis of sex hormones begins, the girls have estrogen, the boys have testosterone.

This week the baby will officially be called a fetus, but for now we call it an embryo. This period is considered the end of the first critical period. Now the dangerous effect of drugs, leading to malformations, is not so significant.

The woman's breasts are enlarged even more, the veins are visible. The tummy is round enough to think about comfortable clothes. The uterus continues to grow with the baby, so the pressure on the pelvic organs increases. Uterus has the size of grapefruit, but pregnancy is not yet visible to others.

It is important to maintain a positive attitude, pamper yourself with gifts, do not worry about changing the shape of the body. It is worth picking up beautiful clothes, clothes, to continue to feel beautiful and happy.

Mom is a toxicosis phenomenon. In connection with changes in nutrition, metabolism, muscle tone and hormonal changes, the figure and body movements can change.

11 week

From 11 to 13 weeks, the baby undergoes a serious medical examination - ultrasound screening. Determine the thickness of the collar space, nasal bones, conduct a study of the vessels, exclude gross changes in the structure of the body. Inspect the internal organs, the structure of the face, the brain, arms and legs, the spine.

Your baby is the size of a fig, and the doctor paints the anatomy of the fetus with such details! The head is still large relative to the body, but the proportions continue to change: the head is large, the body is small, the upper limbs are long, and the lower ones are short and bent at the knees. Appear rudiments of nails and teeth.

The fetal heart beats very often - 140 beats per minute. The growth of blood vessels in the placenta is activated, the child is growing rapidly and requires more nutrients. There is a formation of auricles, hair bulbs are laid.

With the results of ultrasound, a biochemical blood test is performed on chromosomal abnormalities and the risk of complications of pregnancy.

For future mothers suffering from toxicosis, gradual relief begins. Already by the 14th week the morning discomfort should pass. Increased urination is a normal reaction of the body to hormonal changes. You need to drink clean water, as well as healthy drinks, it is better to limit the products containing caffeine. You can also start( if there are no threats) to engage in fitness for pregnant women, and use oils from stretch marks, the most effective are almond, sesame, olive.

Symptoms of toxicosis are replaced by new sensations: heartburn, bloating, there may be constipation.

12 week

Your baby is about the size of a lime. Until 11-12 weeks, there are no reliable ultrasound differences between boys and girls. The probability of correctly determining the sex of the fetus is already above 50%.The weight of the fruit is about 20 grams, and the length is about 9 cm.

At this time, the baby begins to actively move his hands and feet, hands, fingers. In connection with active growth, the intestine ceases to fit in the tummy and starts to form in loops. In this period the intestine trains: through it passes the amniotic fluid that the fetus swallows. White blood cells appear in the blood - leukocytes, which carry the function of protection against infections.

Gradually, the baby strengthens the lungs, the work of the gastrointestinal tract is established. The kid tries to lift his head, can already suck a finger. Appears sensitivity to pain, responds to sounds.

Mom's weight gain by the 12th week of pregnancy is about 1-2 kg. Doctors recommend gymnastics for pregnant women, swimming is indicated.

The end of 3 months makes you forget about the risks that existed since the day of embryo conception. This is the time when a woman has already got used to a new state and can enjoy it.

In the exterior there are notable transformations. The skin is more fresh, elastic, the hair grows better, they become thicker, silky. Many pregnant women forget about rational nutrition, believing that during this period you can afford everything.

Recommendations of food habits:

• should forget about harmful fast food, snacks, street food, spicy, spicy, fatty foods can lead to constipation, affect the baby's condition;
• does not overeat, trying to fulfill the norm for two, excess weight complicates the process of childbirth and subsequent rehabilitation;
• you need to forget about your own taste preferences, eating cottage cheese, fish, low-fat meat, nuts, fruits, vegetables.

Week 13

Pea pod - so you can describe the size of the baby in household measurements. Or 7-10 cm, 20-30 grams. From the 13th week begins the second trimester of pregnancy. All the main organs and systems are already formed, all the rest of the time before the birth the organs will grow and develop. The child can react to temperature changes, light, music, noise, pain.

Physiological development:

• bones continue to harden, and muscles grow and improve;
• appears a dream, it lasts only a few minutes;
• motor activity includes various movements, except flexion can cross limbs, do chaotic mahi;
• face becomes more like human;
• ears are moving closer to their place from the neck, and the eyes are lateral to the center of the face;
• the first hairs appear.formed all 20 milk teeth;The
• head is still disproportionately large, but now the body will grow faster;
• hands continue to grow, the kid can already reach to the face.

Often, doctors at the time of ultrasound show parents how the baby puts a finger in his mouth.

At this time the shape of the abdomen changes, the former clothes become cramped. Those around can notice the new emotional mood of a woman, she becomes more relaxed and relaxed.

The trimester starts, the same recommendations on nutrition and moderate physical activity remain. A woman can notice the finally fading line of the waist, and the breast that has increased several sizes. You need to pick up special underwear, often from the nipples are observed discharge - it's colostrum. You can forget about frequent trips to the toilet, lifting the uterus relieves uncomfortable sensations. When there is a pulling pain in the lower abdomen and lower back, you need to turn to the gynecologist. Allocations normally remain white, clear, without sharp odors.

14 week

At week 14, the fetus grows to 13 cm and 45 grams. The boys form the prostate, and the ovaries of the girls fall into a small pelvis. The sky is already fully formed, active reflex sucking begins. The baby simulates breathing movements, so that after birth it is effective to take the first breath.

The formed pancreas begins to produce the most important hormone of carbohydrate metabolism - insulin. And in the depth of the brain begins to work pituitary - the head of all organs of the endocrine system, it later controls all the glands of the body.

The baby has a pronounced facial expression, as well as clear sleep and wakefulness regimes. Heart rhythm often depends on the behavior of the mother. Her bad habits and stresses can lead to a noticeable increase in the heartbeat of the fetus.

If ultrasound has not yet been passed - it's about time. The doctor can accurately measure the parameters of the child, determine compliance with standards.

The future mother is gradually all fears and doubts. She learns to enjoy the harmony of life, there is a reassessment of priorities. The uterus continues to rise( it is 10-15 by itself above the pubis), and the breasts grow. A woman already needs to choose more loose and comfortable clothes.

At this time it is not necessary to indulge in sweet, it is better to provide the child with high-quality protein. Average norms of gaining weight 1.5-2 kg from conception, it is important to follow the arrow of the clock and not overeat.

We recommend the use of special cosmetics for the abdominal skin.

15 week

The size of the fruit is with the apple, its weight is about 70 gr. The whole baby is covered with fine hair, which is on the back, shoulders, ears, on the forehead. These hairs contribute to the preservation of heat. Then, when the baby gets a sufficient layer of adipose tissue, the hairs will fall off.

The child builds various grimaces, frowns, frowns, squints, but this does not reflect his mood at all. He is constantly changing his position, moving actively. But the baby is too small and does not get to the walls of the uterus. There is a unique pattern of skin at the fingertips and special proteins on the red blood cells that determine the blood group.

The baby's dream is short-lived. The eyes are still closed, but the optic nerves are formed, the child can distinguish light and shadow. Sweat glands work.

The future mother continues to lead an active lifestyle, not forgetting to monitor her health. Discomfort can be connected:

• with the state of the teeth, it is necessary to go through the dentist, cure caries, bleeding gums, to prevent the occurrence of infection;
• reduced immunity leads to respiratory diseases, it is important to limit trips to public places, if symptoms appear, the doctor will advise safe medicines;
• weakness, a desire to relax, sleep - it is typical for such hormonal changes, do not deny yourself, because when a baby is born, sleep will become a luxury;
• with an increase in the veins you need to choose the right shoes, you may need an easy gymnastics to relieve fatigue;
• pain in the lower abdomen is not always associated with abnormalities, uterine growth affects the stretching of muscles, ligaments;
• may cause pigmentation on the abdomen.

16 week

The size of the kid reminds an avocado. Skeletal bones become harder, but flexible enough for the baby to pass through the birth canal. The umbilical cord contains one vein and two arteries, surrounded by gelatinous substance, which protects the vessels from clamping and makes the umbilical cord slippery for movement. Girls these days are formed sex cells - your future grandchildren.

The fruit becomes more like a baby. His body covers an easy fluff, the skin is still thin, the vessels are visible. The height is 11-14 cm, and the weight reaches 110 g. The chemical composition of the blood changes, erythrocytes, platelets, lymphocytes appear, hemoglobin is synthesized. On the face all the features are already clearly pronounced, eyebrows and cilia appear. The fruit is covered with a special white lubricant, which protects the delicate skin until the birth process itself.

Future mom continues to monitor their diet, sudden weight increases will lead to dangerous pressure changes. The walk becomes like a duck, there is fatigue in the legs. If pregnancy is not the first, you can already feel the wiggling of the fetus. Weight gain for this week of pregnancy is 2-3 kg.

17 week

The size of the baby is 12-13 cm and the weight is up to 150 g, the size of a turnip. Hands and feet are commensurable with the size of the body and head. Under the skin begins to be deposited fat, sweat glands develop. The placenta provides the child with vitamins, minerals, proteins, fats and oxygen, removing waste products.

The baby spends more time, and then stretches and grimaces. It responds well to sounds, sharp, loud - scare, mom's voice - will reassure. The pituitary gland and adrenal glands are active, the formation of internal reproductive organs begins in girls.

Because of the increase in the volume of circulating blood, maternal heart palpitations can occur. In this case, pay the doctor's attention to this, to see if everything is in order.

The woman's performance decreases. She needs support of her people more than ever. Heaviness, pain in the sacrum, weight gain, affect the activity of the mother, her rapid fatigue. Periodically, it can throw in the heat, then in the cold, sudden changes in mood - characterized by accumulated fatigue. It is important not only to support the husband, but also all relatives, someone can cook soup, someone can take the documents to the hospital.

18 week

Your child is the size of a Bulgarian pepper( 18 cm) and weighs 250 grams and is ready for communication. Yes, now the kid can hear, and a loud sound can scare him. He gets used to the voice of his parents, and soon he will be able to recognize it from other sounds.

The endocrine system of the fetus is actively developing and functioning."Children's" hormones are so many that the baby can even supply the mother's body.

It is important to talk with the baby, it stimulates the development of his central nervous system. Mom can feel the first tremors in the period of activity, the musculoskeletal system develops. Unique fingerprints already appeared on the fingers.

Mom this week can for the first time feel the wiggling of the fetus. While they are weak and infrequent, do not worry if you do not hear the baby too often.

Mom's tummy is quite pronounced and she has to choose the posture for sleep, the most favorable for delivery is the left side. A good appetite should be restrained, during this period there is a significant increase in weight. Carbonated drinks and large amounts of servings are fraught with constipation and swelling. The greater need of calcium can affect the condition of the teeth, so the diet is necessarily the presence of fermented milk products.

Sensitivity of the breast, darkening and widening of the areola, increase in size, provoke depression. Do not despair, after childbirth, with the observance of a rational diet, you will quickly come back to normal.

19 week

Fetal growth is 25 cm, and weight is already 250-300 grams. For most of the day it sleeps, and during wakefulness one can feel its movements. If the mother walks, it's the baby crouching, but it's worth it to lie down to rest - immediately felt jerks. Sebaceous glands continue to produce a white protective grease.

Raw grease covers the baby's skin and helps regulate body temperature. There is a laying of molars, they are under the rudiments of dairy. The head does not grow so fast, but the limbs and the body continue to grow, so the baby becomes more symmetrical.

Mom finally retreated toxicosis and heartburn, but it can be troubled by the itching of the skin of a growing abdomen. Uterus is 1-2 cm below the navel. In connection with its intensive growth, there may be painful sensations associated with stretching the ligament of the uterus. It is worth using a special cream or oil, to reduce the sensitivity.

With fatigue and cramps in the legs can be prescribed drugs Magnesia. With back pain, relaxing exercises help. It is important to alternate the regimes of activity and rest. If there are no threats and pathologies, you need to walk a lot, do your hard work. Self-appointed bed rest, can complicate the process of childbirth due to muscle weakness.

At this time, it is necessary to pass a urinalysis test and a planned second ultrasound. On it you can already accurately know the sex and get a photo of the baby.

20 week

The kid weighs about 280 gr., His height is 22-25 cm, he can not only yawn and somersault, but also play. The legs become longer and proportionate to the body, the head gradually becomes smaller. The skin is compacted and consists of 4 layers already, the protective grease continues to be produced. Nails appear on the handles and legs, the first hairs on the head.

Especially good at this time the baby is given flexion and extension of the arms and legs. He becomes more and more like his parents.

Now is the rest period for the future mummy, she enjoys her condition and blooming appearance. The tummy is small, neat, does not interfere with the movement and do the usual things. On the sensations the woman can understand, how the kid develops. Strong intense shocks will signal a lack of oxygen, you need to go to fresh air or to ventilate the room. If this happens after physical activity, you need to rest and then the baby will calm down.

It is recommended that a woman is already sleeping on her side to avoid vein transmission. At the heart of food are foods rich in calcium and iron - beef, buckwheat, cottage cheese, spinach, prunes. Week 20 is the equator of pregnancy. The growing uterus tightens the internal organs, so the mother faces shortness of breath, frequent urination.

In these weeks, my mother visits another routine ultrasound, doppler is performed. This is a good time for ultrasound on the video and next photo of the heir.

Ultrasound in the 20th week: the sex of the baby is the boy

Ultrasound in 20 weeks: the sex of the fetus is the girl

21 week

The fetus grows 25 cm and the weight is 400 g. Outwardly, he already looks like a newborn, it only remains to gain weight and grow. Amniotic fluid allows the baby to learn what the mother ate for dinner. When the fetus moves on the stomach, noticeable tubercles may appear.

Most of the nutrients to the baby come from the placenta. If there is an ingestion of the amniotic fluid, the stomach is already equipped to digest it and obtain nutrients. The baby begins to taste.

Mom adds more weight, as there is an intensive growth of the baby.

The most interesting thing at this stage is the opportunity for mom to form future taste preferences of the child. If you eat spicy, spicy, salty sweet dishes, you'll have to make a lot of effort after the baby tries the broccoli, buckwheat or carrots.

For mother, there are problems with flatulence, a load on the veins and control of appetite. Extra pounds can lead to a large fetal size and complications during childbirth.

About how the fetus is located, will tell on ultrasound.

At birth, doctors assess the child's condition on several parameters: activity, muscle tone, palpitation, respiration, skin color, reflex reactions. The more points, the more healthy your baby was born.
