Doctor's answer:
Last menstrual period calculation method: Subtract 3 from the month of the last menstrual period (add 9 if it's less than 3) or directly add 9 to the month, and add 7 to the day to determine the estimated due date. For example: If the last menstrual period started on March 5th, the estimated due date would be December 12th of the same year.
