Patient's question:
Patient Gender: Menstrual cycle of 90 days. How to calculate ovulation period?Detailed medical condition and consultation purpose: I want to know how to calculate the ovulation period. First question supplement: I don't want to use basal body temperature to calculate the ovulation period. Can I calculate the ovulation period based on the number of days?
Doctor's answer:
Hello. For women with irregular periods, ovulation usually occurs around the 9th day after the end of menstruation, and the ovulation period generally lasts for about 10 days. However, a more accurate method is to use ovulation test strips, which are typically started 3-4 days after the end of menstruation. Ovulation can also be determined through methods such as observing cervical mucus, tracking basal body temperature, or using ultrasound monitoring.
