Ovulatory bleeding is clinically abnormal whenever it occurs. Ovulation bleeding clinically mainly manifests as a small amount of vaginal bleeding, which is far less than the amount of menstruation, and without the use of antiemetic drugs or clinical intervention, the bleeding will stop on its own in 3-5 days. This is because during ovulation, the estrogen and progesterone in the body drop temporarily, so that the endometrium will be more sensitive to the drop of estrogen and progesterone, and retreating bleeding will occur. When the estrogen and progesterone in the body return to their original levels, the bleeding will stop naturally. Therefore, having ovulatory bleeding is clinically abnormal and requires intervention.
