The term “great aunt” refers to menstruation. Ovulation bleeding is usually followed by menstruation on the 14th day, and this is mainly for women who have regular periods. If a woman usually has regular periods, then ovulation is also more regular. Ovulation usually occurs on the 14th day or so before the next menstrual period, and after ovulation comes the luteal phase, which lasts for about 14 days, and after the luteal phase comes menstruation. Therefore, menstruation comes 14 days after ovulation bleeding. However, menstruation can be delayed or advanced due to various factors. Not everyone will have bleeding during ovulation, but a few people will have a small amount of vaginal bleeding, but the amount of bleeding is not much, which is a normal physiological phenomenon and does not need special treatment. If the bleeding is heavy and the color is abnormal, you need to go to the hospital for a comprehensive examination.
