Pregnancy is one of the difficult stages experienced by women, it is difficult and stupid and contains a lot of pain and suffering and fatigue and exhaustion, but most frightening of the pregnant is the date of birth.
The number of women if not all women fear this day because it comes in a sudden way, and accompanied by pain and anxiety and fear, but remains trust in God is the only thing that benefits these moments.
The approximate gestation period from the day of fertilization until birth is 266 days. The gestational age of the pregnant woman, which is normal and regular every 28 days, is 10 months, or forty weeks. It is known that the normal gestation period is nine months, .
Depending on the first day of the last month of pregnancy, three months will be subtracted from the date of the first day of the last cycle and the addition of one week, resulting in our expected date of delivery. However, there is no guarantee that a pregnant woman will be born 280 days after the pregnancy, since her birth rate is only 5%, while the probability of her birth within two weeks before or after the calculated date is about 85%.
If the session is less than 28 days, however, the expected date of the session will be a few days earlier. If the duration of the session is more than 28 days, the expected date of the event will be a few days late than the date calculated.
It is important to note that all this is expected for the birth date and not the instantaneous confirmation. Therefore, the pregnant woman must not rely entirely on these accounts, but rather monitors herself so that her labor will not come to her and she is not prepared or disappointed.
One of the precautions that helps to calculate the date of birth is the initial internal examination. It is proved that the size of the uterus is identical to the calculated period of pregnancy, which is attributed to the first day of the last menstrual period. It also helps to hear the heartbeat of the fetus. As early as the twelfth week (the end of the third month).
