Patient's question:
Today is the first day. My period usually lasts for 5 days, with a cycle of 25, 26 days. Treatment history and effect: 4 months ago, I had a natural miscarriage, and there were no problems with an ultrasound. What kind of help do I need: Could you please tell me which days this month are my ovulation period?Doctor's answer:
Female ovulation is influenced by the cyclical changes of endocrine hormones secreted by the pituitary gland and ovaries. The lengths of both cycles are consistent, occurring once per month, with ovulation occurring between two menstrual periods. While the duration of a woman's menstrual cycle can vary, the interval between the day of ovulation and the start of the next menstrual period is relatively fixed, generally around 14 days. Based on this relationship between ovulation and menstruation, it is possible to estimate the fertile period by calculating the menstrual cycle. The calculation method involves starting from the first day of the next menstrual period and counting backward 14 days or subtracting 14 days to determine the ovulation day. The fertile period is then defined as the ovulation day plus the previous 5 days and the following 4 days. This is also the theoretical basis for the safe period method of contraception, as the time outside of the menstrual period and the fertile period is considered the safe period.
