What days are the ovulation period in a 28-day menstrual cycle?

Patient's question:

No

Doctor's answer:

Hello, the calculation method for ovulation is to start from the first day of the next menstrual period, count backwards 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) together are called the ovulation period.
