After women discover they are pregnant, they need to calculate the due date. The most commonly used method for calculating the due date is based on the last menstrual period. If a woman's menstrual cycle is not very regular, the expected delivery date can be estimated through fetal movement and ultrasound examination. So, how many days is the normal due date?
The normal due date is 40 weeks of pregnancy, which means that women give birth after 280 days of pregnancy. However, the due date is a reference time and not an accurate production date. And the due date is not very accurate, so pregnant women don't need to worry about not giving birth when they reach the due date.
It is difficult to accurately determine the time of conception for women, so the estimated due date is only a rough estimate and may not be completely accurate. Therefore, it is normal for there to be differences from the actual delivery time. From a medical perspective, the total duration of a woman's pregnancy is 280 days, divided into 40 gestational weeks.
The due date only indicates the approximate delivery time for pregnant women, usually 2 weeks before and after the due date, which is a very normal situation. The term full-term fetus commonly referred to refers to babies born between 37-42 weeks of gestation. About 80% -90% of pregnant women will give birth during this period, so it is common to give birth earlier or later than the due date. If a baby is born before 37 weeks, it is considered premature. Usually, the shorter the gestational age, the poorer the baby's physical condition.
