Patients who have bleeding during ovulation can conceive. Bleeding during ovulation is mainly caused by a transient decrease in estrogen after ovulation and does not mean that the patient is ovulating abnormally. A small amount of bleeding does not affect the patient’s ability to have intercourse, but she should pay attention to hygiene during intercourse, as long as it does not cause infection, there is no big problem. Before ovulation, the patient’s estrogen level should reach 200 pg/mL and be maintained for 48 hours before the patient has normal ovulation. After ovulation, the patient’s estrogen will drop rapidly, so the endometrium will lose the support of high hormone level and will be stripped and bleeding, but after ovulation, the corpus luteum will secrete estrogen and progesterone, making estrogen and progesterone rise, and the endometrium will gradually repair with the support of high hormone level. The endometrium is gradually repaired with the support of high hormone levels. In some cases, the bleeding is only brownish discharge or spotting, and it clears in 3-5 days.
