Pregnancy is a very special time. A woman in this state becomes mysterious, sentimental. It is easy to guess about her interesting position: if you ask about some time period in your life, pregnant women all count in weeks. That is, the expectant mother will immediately answer what her gestational age is by week. Which month is the due date? Pregnant women often answer this question after a pause.

Usually find out about pregnancy is obtained at 4-5 weeks, not earlier. It has to do with physiology. When a delay occurs, a woman begins to listen to her body, buys a test. This corresponds to a period of 4-5 weeks of pregnancy. But some feel pregnancy much earlier. Such women are able to "calculate" their interesting position even before the delay. This is quite possible if you are very attentive to yourself, because the changes associated with the onset of pregnancy begin from the moment of fertilization.

Months and weeks: let's figure it out

The gestational age by weeks and months is 40 weeks or 10 months. Meaning 10obstetric months. This value differs from the standard calendar months, which are 9.

What is the reason for this difference? The starting date for calculations during pregnancy is the first day of the last menstruation, and not the day of conception. It is almost impossible to accurately determine the moment of conception, so doctors have adopted this practice of calculating the gestational age.

Trimesters of pregnancy

The total duration of pregnancy is divided into trimesters.

I trimester - 1st to 13th week;

II trimester - 14th to 27th week;

III trimester - from the 28th week until the birth of the baby.

Each of the trimesters of pregnancy has specifics and features that every pregnant woman needs to understand.

I trimester

The first trimester is the most responsible in terms of the formation of all the important systems of the baby. At this time, the woman gets used to the new state. The gestation period by weeks and months corresponding to the first trimester is 1-3 months.

There may be changes in the psycho-emotional state, mood swings. Signs of toxicosis also manifest themselves: nausea. Pregnant women often report drowsiness, dizziness, headaches during this period.

Since the first trimester is the most dangerous, you should take care of yourself as much as possible and try to avoid any diseases. A common cold at such a time can lead to a miscarriage. To do this, if possible, avoid visiting crowded places, use preventive measures.

First Screening

Ona period of 10-13 weeks, a woman undergoes the first screening. This is the most important examination, during which serious pathologies of fetal development can be detected. An ultrasound specialist analyzes the parameters of the fetus, checks how developed all the vital systems are, be sure to donate blood for tests.

II trimester

The gestation period by weeks and months, corresponding to the second trimester, is 4-6 months. By the 14-15th week of pregnancy, the formation of the placenta is completed, and the fetus becomes less vulnerable. It begins to actively grow and develop, receiving all the necessary nutrients from the mother through the placenta. All organs have already been laid in the first trimester, now they are being improved. At this time, the stomach is rounded, becomes noticeable.

After 15 weeks, you can reliably find out the sex of the unborn baby.

In the second trimester, a second screening should also be done. It is carried out for a period of 16-20 weeks. The state of the placenta, the size of the fetus, the degree of development of internal organs, the amount of amniotic fluid are analyzed.

30 weeks pregnant: time for maternity leave

So time has flown by, the 30th week of pregnancy has come. How many months is this? This period corresponds to 7, 5 obstetric months or 7 calendar months.

In Russia, sick leave for pregnancy and childbirth is issued to women exactly at 30 obstetric weeks, in the case of multiple pregnancy - at 28. To do this, you need to apply for a sick leave at the place of pregnancy and provide itemployer, write an appropriate application. Sick leave during normal pregnancy is given for 70 days before childbirth and 70 days after childbirth, that is, for a total of 140 days. The maximum length of sick leave for pregnancy and childbirth reaches 194 days. This is the case when the fact of multiple pregnancy is detected only at the time of childbirth. Paid sick leave in the total amount within 10 days from the date of provision to the employer.

III trimester

This is the final period of bearing a child. At this time, the woman begins to visit the doctor conducting the pregnancy more often, undergoes a lot of examinations, and prepares for childbirth.

The gestational age by weeks and months is 40 weeks and 9 months. But these figures, as we have already understood, cannot be considered accurate, since childbirth during the normal course of pregnancy can occur at a period of 38-42 weeks. Today, more and more women are carrying their baby to 41-42 weeks. This does not alarm doctors, because up to 42 weeks, if everything is in order with mom and baby, doctors do not interfere in the natural process.

The most important characteristic of the time period during pregnancy is the duration of the pregnancy in weeks and months. Photos of different periods of pregnancy will become an invaluable memory. Have an easy pregnancy, uncomplicated delivery and, most importantly, a he althy baby!
