Black discharge from the leukorrhea suggests that there is a small amount of vaginal bleeding, which may be caused by ovulation bleeding, endometritis, cervicitis, preeclampsia, and so on.
1. Ovulation bleeding: women may experience a small amount of bleeding during ovulation, which is usually small and lasts for a short period of time and can stop on its own.
2. Endometritis: Infection of the uterine lining, resulting in localized inflammation. Due to the stimulation of inflammation, it may lead to local congestion and edema, and if the capillaries rupture, a small amount of bleeding may occur.
3. Cervicitis: local inflammatory stimulation of the cervix may also lead to cervical bleeding and black discharge.
4. Pre-eclampsia: Vaginal bleeding may occur in the early stages of pregnancy due to maternal hormonal deficiencies, external stimuli, etc., leading to embryonic instability.
There may be other reasons for the black discharge from the leukorrhea, so it is recommended to go to the hospital in time to find out the reasons under the guidance of a professional doctor and carry out targeted treatment.
