Waiting for the birth of a new life is an exciting period in the life of every woman. But any future mother is worried about how the pregnancy should go and how the baby should develop in her stomach. This article will cover the main facts about how the 19th week of pregnancy goes. Photos of the fetus will also be posted below.

Second trimester of pregnancy

From the first weeks after conception, changes occur in the woman's body. But already in the second trimester (from 13-14 weeks), the condition becomes more stable. Most often, morning sickness and dizziness pass. Pregnancy of 18-19 weeks proceeds more calmly, the fetus has already taken root in the mother's body and continues to develop actively. However, you should treat your situation responsibly, avoiding stress, physical exertion and injuries. At this interval, there is a small risk of preterm birth.

How to correctly calculate the gestational age and date of birth

Most of the ladies, who first learned about their situation, begin to calculate the date and date of birth. But you should know that there is also an obstetric term for carrying a fetus, according to which the pregnancy lasts not nine months, but 41 weeks, that is, more than nine. The gynecologist starts counting the course of pregnancy from the date of the beginning of the last menstrual cycle. Usually, the difference between the midwifery period and the mother's calculations is about two weeks. Following these rules, it is quite easy to find out the approximate day of the baby's birth.

19 week of pregnancy, how many months are left before delivery according to the obstetric calendar? After making calculations, it turns out that this is the end of the fifth month, therefore, there are still four more before the birth. However, the development of the fetus is determined by the embryonic period, that is, the count goes from the week when conception occurred. The fetus should correspond to 17 weeks of development.

Pregnancy 18-19 weeks. Features of the growing belly

Before the beginning of the second period of fetal development, the abdomen is almost invisible, since the baby is still very small and the uterus has only slightly increased in size. The stomach at the 19th week of pregnancy becomes much larger, which limits the future mother in the freedom of movement. It becomes difficult to bend over, stay in one position for a long time and sleep. The uterus begins to press on the internal organs of the pregnant woman. Very often there are heartburn, constipation and frequent urge to urinate. Great attention should be paid to the food consumed, since from this moment the doctor begins to strictly monitor the weight of the woman carrying the baby. It is important to take a responsible attitude to the position occupied during sleep. It is undesirable to sleep on your stomach or back, because this can harm the fetus. In the "lying on your stomach" position, there is a risk of damaging the fetus, and in the "lying on your back" position, there is a high probability of pinning down the aorta, through which oxygen is supplied. You should rest, lying on the side where the baby is located.

At each medical examination, starting from the second trimester, the doctor should measure the abdomen. Its volume directly depends on the size of the fetus, uterus and the amount of amniotic fluid. Of course, each woman during pregnancy has its own individual characteristics, depending on her body type and body weight before pregnancy. But there are certain permissible norms.

The abdomen at the 19th week of pregnancy, when measured vertically, reaches 18-20 cm. The uterus is already beginning to rise to the navel. These data are provided only for single-pregnancy pregnancies.

If the doctor notices deviations from the norm, then the pregnant woman is sent for additional examinations. Since the cause of the increase in the abdomen may be too much amniotic fluid or other abnormalities.

What changes occur in the fifth month of pregnancy

A woman waiting for the birth of a child, by the fifth month already gets used to her condition. Time flies, the first period is already over, the 19th week of pregnancy has arrived. What happens to the child's body at this moment?

Within five months, the fetus developed from an embryo to a small human. At this time, the baby has already formed arms, legs, fingers, ears, the shape of the head and parts of the face. Also, the respiratory, digestive and nervous systems, the subcutaneous layer, and the rudiments of teeth continue to form.

If before this period, the mother has already felt the first movements of her child, now his movements will become more confident and clear. And some expectant mothers will only have to enjoy the first thrusts and kicks. The child's brain is already actively developing. The embryo begins to move in the abdomen, very often changes its position. In connection with the beginning of brain activity, the movements of the fetus become more concentrated. It is possible to show a reaction to the sounds of the parents voice and the touch of hands on the stomach.

Second ultrasound examination of the fetus

As a rule, in the second trimester of pregnancy, in addition to all the usual examinations, an ultrasound examination of the fetus is also performed.

At the first routine examination, the doctor confirms the presence of a normal pregnancy (not intrauterine or frozen), specifies its duration, determines the age of the fetus and the sex of the child (the probability of determining the sex of the fetus is very low).

The ultrasound procedure at the 19th week of pregnancy is carried out to identify possible pathologies in the embryo and to examine its anatomical development. This study also determines the position of the fetus in the womb, which plays a big role in how the birth will take place. Also, with the help of the device, the doctor performs fetometry, that is, determines the size of the circumference of the head and abdomen, the bones of the arms, legs, thighs, shoulders. The symmetry of the external and internal organs is seen. The determined sex of the child has a probability of up to 90%.

Based on the data recorded by the specialist, it is concluded that the development of the fetus corresponds to its embryonic age. In addition to studying the parameters of development, the doctor examines the state of the uterus and placenta. When pathologies are detected, the gynecologist, based on the results, makes a diagnosis and prescribes treatment.

Norms of ultrasound readings.

• BPR - from 40 mm to 50 mm;

• LSD from 53,5 mm to 60.5 mm;

• OG from 140 mm to 180 mm.

• DB - 25 mm to 35 mm;

• DG - from 23 mm to 31 mm;

• DP from 20 mm to 26 mm;

• coolant from 125 mm to 155 mm;

• NK - from 5.2 mm to 8.0 mm;

• tall - about 22.1 cm;

• weight - 230 g to 320 g.

During the second ultrasound examination, the 19th week of pregnancy comes to an end. A photo of the child can be obtained from a doctor. In the picture, you can already see the formed little man, all parts of the body are clearly visible. Modern technology allows you to make a 3D photo of the fetus.

Pregnancy 19 weeks. Fruit size

When a pregnancy of 19-20 weeks passes according to the appropriate standards, the embryo already reaches a height of 20-22 centimeters. It's about the size of a banana. The weight of the crumbs is 240-300 grams. The baby grows all parts of the body.

As described in the norms of ultrasound results, during the period when the pregnancy is 19 weeks, the size of the fetus has already increased significantly. Circumference small head is an average of 160 mm, femur length - 30 mm, length of the Shin - 25 mm, arm length - 24 mm. The circumference of the tummy is approximately 140 mm. The length of the nasal bone is also very important, it has a size of about 8 mm. The fingers of the hands and feet grow. The foot is already formed. Its length reaches 2.5 mm, and from this stage its size will remain the same until birth.

From the 20th week of pregnancy, the fetus begins to actively gain weight and grow. By the time of delivery, the average weight of the baby is 3000 grams, and the height is 50 centimeters.

Development of the fetus

By the end of the fourth month after conception, the baby had not yet opened his eyes. However, he can already distinguish between light and dark, and can turn to a strong light source. By this time, the baby is able to move knives and handles, he begins to eat, turn over, constantly changes his position. In a few weeks, the mother will be able to see how the heel, elbow or butt of her miracle protrudes on her stomach. The fetus is able to raise and turn the head, the grasping reflex is developed. His sleep is about 18 hours. While awake, he learns about the world around him. From now on, your favorite activity will be sucking your finger. This is the remarkable 19 week of pregnancy. A photo taken on an ultrasound can capture this amazing moment. Pregnancy of 19-20 weeks proceeds calmly, but the expectant mother should be attentive to the state of her health and limit physical activity.

It is very important that the mother's body has enough calcium and iron. For the normal growth of the bones of the embryo, a pregnant woman should use vitamins prescribed by the gynecologist under whose supervision she is.

The role of the fetal position in the upcoming delivery

For a woman carrying a child, at 19 weeks of pregnancy, the location of the fetus becomes no less important than its growth and development. There are three options for the position of the baby in the womb.

At 19 weeks of pregnancy, the location of the fetus is not constant. Since the size of the embryo is not yet large enough, it has enough space in the uterus to periodically change its position. Therefore, at this stage, the doctor will not worry.

At 19 weeks of pregnancy, the location of the fetus can be transverse, angular, and pelvic. But before the birth of a child, there is a lot of time and the baby is able to turn over at any time and more than once.

Head presentation

The head is located in the direction of the birth canal. This option is considered the most favorable, since the head is the largest part of the body of the developing embryo and the most difficult to get out during childbirth. After the exit of the head, the body easily leaves the womb. If the fetus took this position closer to birth, then this is 90% of successful births.

Pelvic presentation

In this case, during childbirth, the pelvis first comes out, and then the whole body. Since, as mentioned above, the head is the largest part of the baby's body, the birth process becomes more complicated. Very often, with pelvic diligence, the doctor decides on a caesarean section.

If the location of the fetus is pelvic at 19 weeks of pregnancy, then you should not worry too much. At the age of 17 weeks, the baby does not yet occupy the entire uterine cavity, and this gives him complete freedom in the possibility of changing his position.

Transverse presentation

In this situation, the head and butt of the fetus are located on the sides of the uterus. That is, it lies across relative to the birth canal. This case is the most difficult. Because with this diagnosis, the process of natural childbirth is impossible. The baby is born only by caesarean section.

Until the pregnancy has reached 30 weeks, the expectant mother should not worry about how her child lies. At 19 weeks of pregnancy, the location of the fetus is unstable. And until the third trimester, no effort should be made to change the situation. The baby can take a headache even a couple of weeks before delivery.

Recommendations for pregnant women

While carrying a child, a woman should treat her health with special attention. The body of a lady in a position needs constant replenishment of useful substances. Therefore, the diet must include cottage cheese, liver, meat, eggs, fish, fruits and vegetables. In any case, you can not smoke, drink alcohol and antibiotics. Every morning you should start with a light warm-up.

For excellent health, you should take daily walks in the fresh air, relax several times a day and do what you love. The important role played by positive emotions and peace of mind. During the entire pregnancy, from the moment of registration, you should regularly visit a gynecologist and follow all the instructions. In case of any complications, you should immediately contact specialists for help.
