Patient's question:
NoDoctor's answer:
Ovulation is when pregnancy is most likely to occur. The interval between the day of ovulation and the start of the next menstrual period is relatively fixed, usually around 14 days. Based on this relationship between ovulation and menstruation, it is possible to calculate the ovulation period based on the menstrual cycle. This is done by starting from the first day of the next menstrual period and counting backward 14 days to determine the day of ovulation. The day of ovulation, along with the 5 days before it and the 4 days after it, together constitute the ovulation period.
