Doctor's answer:
The calculation method for ovulation is to start from the first day of the next menstrual period, count backward 14 days or subtract 14 days to determine the ovulation day. The days before the ovulation day (up to 5 days) and the days after the ovulation day (up to 4 days) combined are referred to as the ovulation period.
