What are the benefits of walking more in the days before due date?

Patient's question:

No

Doctor's answer:

Helpful, the month of the last menstrual period plus 9 or minus 3 is the expected delivery month; the day plus 7 is the expected delivery day. Due to the varying lengths of menstrual cycles in different women, it is normal for the estimated due date to differ from the actual due date by 1-2 weeks. If it exceeds 2 weeks, pregnancy should be terminated.
