Patient's question:
Menstruation came on New Year's Eve, and it cleared up on the fifth day of the first lunar month. Starting from the thirteenth day of the first lunar month, I began using ovulation test strips to track ovulation. The strips only showed the control line. Why is that? [Already married for almost four months, no contraception measures taken, pre-marital health check-up showed no abnormalities]Doctor's answer:
Hello, ovulation generally occurs in the middle of the 28-day menstrual cycle, which is about 14 days before the next menstrual period. If the menstrual cycle is irregular, it is difficult to calculate the date of the next menstrual period, and the 15th day after this menstrual period can be roughly estimated as the ovulation period. Women of childbearing age usually ovulate once per month, which can be alternately released by the left and right ovaries, or continuously released by one ovary. Ovulation is related to factors such as the environment, emotions, physical health status, sexual activity, and contraceptive drugs. Sometimes it may occur earlier, with two eggs released at once, or it may be delayed or temporarily not ovulate. Simply calculating based on the menstrual cycle alone may not yet determine the exact ovulation date. You can buy ovulation test strips to conduct ovulation tests.
