Doctor's answer:
The month of the last menstrual period plus 9 or minus 3 gives the expected delivery month; the day plus 7 gives 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 by 1-2 weeks from the actual due date. If the difference exceeds 2 weeks, pregnancy should be terminated.
