Obstetric pregnancy weeks are a term that helps a woman and gynecologists to follow a child's gestation period. Let's take a closer look at the features of each week of obstetric pregnancy.

As soon as a woman learns that she is pregnant, the first thing she begins to do is calculate her pregnancy. There are two definitions of the gestational age, embryonic and obstetric. And this separation of the definition of the term of pregnancy frightens many expectant mothers.

It should be noted right away that all standards, tables and sizes regarding pregnancy are described and calculated for obstetric weeks of pregnancy. Therefore, it is worthwhile to calculate the obstetrical gestation period, since this is exactly the period that your gynecologist will have, and this period is necessary when you register with a women's consultation. Please note that it is necessary to register at the antenatal clinic for up to 12 obstetric weeks of pregnancy.

Obstetric weeks of pregnancy are determined on the first day of absence of menstruation after the onset of pregnancy. The embryonic period of pregnancy is the term of conception, as a rule, it lags behind obstetric for 2 weeks. So, for example, the obstetric term is 20 weeks, and the embryonic period is 18 weeks. Helps determine the duration of pregnancy and ultrasound based on the size of the fetus, as well as the size of the uterus. Sometimes, the analysis for the level of hCG is used to determine the duration of pregnancy, but it should be performed in the first 12 weeks of pregnancy.

Let's look at the features of each obstetric pregnancy week, which will help to track the changes that occur in the body of a pregnant woman, as well as the development of the baby.

1 midwifery pregnancy week

1 obstetric week of pregnancy indicates that the female body is preparing for fertilization. That is, about 300 thousand eggs are waiting for the sperm. At this time menstruation and restructuring of the whole body begins.

Pregnancy at the first midweek week indicates that the central nervous system is working on the restructuring of the hormonal background. Similar processes occur in the female body every month before fertilization. After fertilization the formation of the future baby begins. And this suggests that the mother's future requires maximum responsibility for her body. 1 Obstetric Week is just the beginning of pregnancy, but this is a very important time, because it is during this period that the body starts to work for two.

2 midwifery pregnancy week

On the 2nd obstetric week of pregnancy, the body is in full swing preparing for fertilization. So, by the end of the second week ovulation begins and it is during this period that the highest probability of successful fertilization. After fertilization has taken place, the woman still does not suspect that she is pregnant.

2 maternity week of pregnancy passes without special symptoms that would indicate pregnancy. The delay in menstruation has not yet come, the hormonal level has not yet departed from the preparation for menstruation, so headache, pain in the lower abdomen and strange eating habits do not cause suspicion of pregnancy.

3 midwifery pregnancy week

3 obstetric pregnancy week as well as the second does not cause a woman's suspicions of pregnancy. Despite the absence of obvious signs, in the body at full speed there are changes. The division of the egg occurs and the immunosuppressive protein begins to be produced. It is this substance that plays a very important role in the third week of pregnancy. If the body did not produce it, then the embryo would be perceived as an alien body, and the immune system tried to destroy it.

3 Obstetric pregnancy week is the period before implantation. In the female uterus, the endometrium grows, while the morula divides and becomes blastic and reliably attached to the walls of the uterus. Please note that this is the most critical period of pregnancy. Since at this point it all depends on how successfully the blastocysts have been implanted into the endometrium. If the blastocyst is not implanted or has not succumbed well to the walls of the uterus, then a woman will miscarry. But the woman will not even suspect that she has a miscarriage, because the body will present it in the form of a slight malfunction of the menstrual cycle. But if the implantation process was successful, then by the end of the 3rd obstetric week of pregnancy, the blastocyst becomes hollow and a small embryo with a tail and a head begins to grow in it.

At the third obstetric week of pregnancy, the future baby weighs about 2 μg, and its height is 0.15 mm. But it is during this period that the kid is laid genes, which are responsible for his weight, height, hair color, eyes, skin and sex. The future mother does not suspect about pregnancy, as external signs are completely absent, the only thing that starts to worry is morning toxemia, which is often taken for problems with the gastrointestinal tract.

4 midwifery pregnancy week

4 Obstetric pregnancy week is the second embryonic week. The first four weeks of pregnancy is a waiting period for a woman who wants to become pregnant, because the body does not give out the "interesting" position of the expectant mother. During this period in the female body there are serious hormonal changes that prepare the body to work for two.

It is on the 4th obstetric week of pregnancy that the expectant mother begins to experience the first symptoms of pregnancy. Irritability, sharp mood swings, strange eating habits, swelling of the chest, a feeling of fatigue and drowsiness, frequent urge to urinate. But sometimes, similar signs of pregnancy are perceived as premenstrual syndrome.

The future baby for 4 weeks of pregnancy is called an embryo and its size is not more than 1 mm. During this period there is a differentiation of embryonic tissues, active development of the child's membranes, placenta and extra-germline structures. So, by the middle of the week blood circulation between mother and child is adjusted, the embryo is firmly attached to the walls of the uterus. The future baby begins to receive nutrients and oxygen from his mother.

By the end of the 4th obstetric week of pregnancy, the features of the child have already formed, there are rudiments of the intestine, lungs, liver, thyroid and pancreas. And it is at this time that the baby forms a vestibular apparatus. If in this period there is a division of the fetus, then the future mother will have twins or twins, if the separation does not go to the end, then the fused twins will be born.

As in the first three weeks, a woman can not say with certainty that she is pregnant. Tests show a negative result, on uzi only the yellow body of pregnancy is visible, which indicates that the body has undergone ovulation. But worst of all, the fact that a miscarriage or spontaneous termination of pregnancy can occur for 4 weeks and the future mother will not find out about it. All will end with a slight bleeding, which the woman will consider for the unexpectedly begun menstruation. And it is at 4 weeks of pregnancy in the body of the baby can be various pathologies. To prevent this from happening, a woman should take care of herself, lead a healthy lifestyle and give up bad habits.

The positive emotions that the expectant mother experiences during this period are very important for the baby, since this kid totally depends on what the mother feels. The hormonal changes in the female body are clearly expressed.

5 Obstetric pregnancy week is the ideal time to learn and make sure that pregnancy develops in the uterus, not in nearby organs. If the pregnancy is normal, then hCG in the blood doubles every day waiting for the baby.
