How long is the normal due date?

We all know that women have a due date when they are pregnant. After this due date, women will give birth, but not all women will give birth on the due date. Sometimes it may be a few days before, and sometimes it may be a few days later. This is all determined according to the physical condition of the pregnant woman. It is normal if the time before or after is not too long. So how long is the normal due date for giving birth?

Nowadays, it is generally normal to give birth a few days before the due date, because once the due date is passed, it will have an impact on the health of both the pregnant woman and the child.

The due date is not the exact date of delivery. The calculation formula for the due date is generally the month of the last menstrual period minus 3 and the date plus 7. If the last menstrual period is September 10, the expected date of delivery is June 17 of the following year. However, because ovulation may occur unexpectedly or the menstrual cycle may be long, the above formula is only a rough estimate and not a very precise calculation. So sometimes, when the due date comes, Maomao seems to still stay in the mother's belly, or he runs out before the due date. But as long as it is between 31 and 42 weeks of gestation, it should be considered within the normal range.

If the due date arrives and there is no sign that the baby is about to come out, the pregnant woman should pay attention to the following: If changes in the placenta, too little amniotic fluid, or changes in the fetal heart rate are found during the perinatal care check, you should not wait any longer and should choose to terminate the pregnancy at this time under the doctor's arrangement. As long as the fetal lungs are mature and the baby is carefully cared for after delivery, do not delay the best time to terminate the pregnancy because of the saying that "one day in the womb is equal to one week after delivery". Otherwise, the fetus may be in danger due to ischemia and hypoxia in the womb.

Of course, there are also some pregnant women whose due date is far from the actual pregnancy period. The doctor can choose the time to terminate the pregnancy based on the B-ultrasound results at the time.
