How long does it take for a pregnant woman to give birth

Patient's question:

No

Doctor's answer:

The due date is calculated from the first day of the last menstrual period, with the entire pregnancy lasting 280 days, or 10 gestational months (each gestational month being 28 days). If a woman delivers between 38 and 42 weeks of pregnancy, it is considered full-term. Since every woman has a different menstrual cycle length, it is normal for the estimated due date to differ from the actual due date by 1 to 2 weeks.
