Ovulatory follicular hemorrhage refers to the localized formation of the corpus luteum after ovulation, and there will be some small blood vessels within the corpus luteum, which will lead to bleeding, and the amount of bleeding may be large or small. In individual cases of heavy bleeding, it can lead to clinical symptoms, such as pain in the lower abdomen, and in severe cases, it can lead to localized rupture, which can cause massive internal bleeding and require surgical treatment. In the majority of women, the formation of corpus luteum and localized bleeding during ovulation is very low, so the majority of women do not have clinical symptoms during ovulation, only increased secretions, without lower abdominal pain or other discomfort. On the other hand, if the follicle bleeds during ovulation and causes localized rupture, there will be very serious lower abdominal pain, and will be accompanied by nausea, vomiting and other corresponding symptoms, we should go to the hospital in time to consult the doctor.
