This question means how many weeks of pregnancy is full term and you can have a normal delivery. You can give birth when you are 37 full weeks pregnant, in other words you can give birth after 37 weeks of pregnancy. You can also say that it is normal to give birth after 37 weeks of pregnancy. Birth before 37 weeks of pregnancy is called preterm birth, and between 28 and 37 weeks falls within the range of preterm birth. Any pregnancy beyond 37 weeks is a normal full-term birth. There are individual differences between people as to when they give birth. Most people give birth around 40 weeks of pregnancy, which is around the due date. There are statistics that between 39 and 40 weeks of pregnancy, the majority of people give birth. So the due date is usually set at 40 weeks, and most people give birth between 39-40 weeks, and if the full-term birth is more than 37 full weeks, it is called a full-term birth.
