Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How is the pregnancy period calculated?Doctor's answer:
In medicine, the estimated 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 pregnant woman delivers between weeks 38 and 42, it is considered full-term. Since the length of each woman's menstrual cycle varies, it is normal for the estimated due date to differ from the actual due date by 1 to 2 weeks.
