Doctor's answer:
Gestational days, gestational age, and estimated due date are all calculated from the first day of the last menstrual period, which does not align with the actual time of pregnancy. The actual time of pregnancy occurs during the ovulation period after the last menstrual period.The method for calculating the estimated due date is as follows: add 9 months (or subtract 3 months) to the month of the last menstrual period and add 7 days to the day of the last menstrual period. You can use the above method to calculate it.
