Calculate the pregnancy calendar by week - nothing is easier

It is worth remembering that the pregnancy period is calculated not from the date of conception, as it would seem, more naturally, but from the first day of the cycle of the last menstruation preceding the conception. That's when the new egg begins to prepare for the release, which will be fertilized at the time of ovulation. Your doctor can find a large number of different tables and graphs that will help in the calculation. In addition to the date of the onset of the last menstruation, they may be asked to indicate the average cycle time for the last 2-3 months (it can range from 21 to 35 days, usually - 28), and the average duration of the second phase - from the moment of ovulation to the end of the cycle. This time interval is from 8 to 16 days. Most often, ovulation is exactly at the middle of the cycle, and you can find out this day by measuring the basal temperature. To calculate your own pregnancy calendar by weeks, you need to know only the date of the last menstruation. In fact, this will be the starting point. Its correct name is the first obstetric week of pregnancy. You will no longer need a calculator. Just mark this date for yourself.

Did you know that you will need to calculate the pregnancy calendar. For weeks it will be convenient to follow the development of the fetus, in advance to know what changes in it and your personal condition is to be expected.

Nothing complicated. Mark each new week in the calendar with numbers. Write down your feelings in a notebook or a pregnancy diary. If this is difficult for you, you can take one of the computer programs with the ability to record.

Do not panic if you did not manage to establish a gestation period immediately. Descend or go on consultation to the doctor. Having carried out an ultrasound study, and also taking blood from the vein to the chorionic gonadotropin, he can most likely name the exact period of pregnancy. The answer is simple - the fetus develops according to known laws. For example, at 6 week a heart is formed, which begins to fight independently. A hormone, even with high variability, still allows you to roughly indicate the date of conception, as with time its concentration increases. So the doctor will be able to calculate the calendar of pregnancy for weeks, based on research data.

As for the analysis for chorionic gonadotropin, this is the only indicator that accurately confirms the presence of pregnancy. By the way, in men this hormone is initially at a higher level. Women - less than 25 units. This will help to calculate the pregnancy calendar. For weeks, the level of hCG varies both upward and backward.

In addition, there are other tests for pregnant women, which any woman carrying a child must pass. This, above all, a common blood test, an analysis of the Rh factor. If you are afraid for the manifestation of hereditary diseases in a child, you can turn to genetic analysis. Taking a miniature sample without harm to the life and health of the child, the researchers will be able to calculate the likelihood of hereditary diseases in your unborn child. If the risk is great, you can decide for yourself whether to leave the child or to terminate the pregnancy. In the presence of serious diseases, this can be done for a longer time. In the meantime, you can independently calculate your pregnancy calendar by week.
