It is normal for a pregnant woman to give birth within 37-40 weeks, because the physical condition and situation are different, so the time of delivery is not fixed, the gestational cycle is 40 weeks, counting from the first day of the last menstrual period, the expected date of delivery is calculated by month minus 3 or plus 9, the date plus 7, to calculate the date of delivery. The delivery between 37 and 42 weeks of pregnancy is a full-term birth, during which all the organs of the fetus are mature, and the delivery is normal at this time. If there are no labor symptoms and no contractions after 1 week from the expected date of delivery, the pregnant woman needs to be hospitalized to plan the delivery and can use oxytocin to induce contractions to complete the delivery. If abdominal pain and contractions occur before the fetus is less than 37 weeks old, it is a sign of preterm labor, so you need to go to the hospital and pay attention to fetal preservation treatment.
