Ovulatory bleeding is a normal physiological phenomenon caused by a brief drop in estrogen levels due to ovulation, which causes the endometrium to lose estrogen support and the endometrium to shed, resulting in regular vaginal bleeding. It usually occurs on the 12th-16th day of the regular menstrual cycle and lasts for a few hours or 2-3 days. The amount of bleeding is significantly less than the normal menstrual flow, and some women may experience mild lower abdominal discomfort or back pain. After ovulation, with the formation of corpus luteum, the corpus luteum secretes estrogen and progesterone, which will quickly repair the endometrium and make the endometrium change towards the secretory phase, the endometrium can thicken and repair and the bleeding stops. Therefore, in general, a small amount of bleeding does not require special treatment. It is sufficient to pay attention to ovulation hygiene, prevention of infection and hygiene of the external genitalia. However, if the bleeding is heavy and lasts for a long time, it is considered abnormal. It is recommended to actively seek medical advice to exclude other reproductive system diseases such as menstrual disorders, cervicitis and cervical cancer, and appropriate treatment is needed. As it occurs during ovulation, it usually interferes with conception. After other diseases are ruled out, oral treatment with a small amount of estrogen, such as Tocopherol, can be given. In addition to this, attention should be paid to keeping a happy spirit, avoiding mental stimulation and mood swings, keeping warm and avoiding cold stimulation and overexertion.
