Bleeding from pelvic inflammatory disease usually stops after 1~2 weeks, which varies from person to person and cannot be generalized. Bleeding in pelvic inflammatory disease is generally due to inflammation and infection of the endometrium, especially when the inflammation spreads to the ovaries, which will cause localized inflammatory reaction of the ovaries, destroying the cells of the ovaries themselves and making the ovaries function abnormally, leading to vaginal bleeding. Generally, after 1~2 weeks of systematic anti-infection treatment, the inflammation will be controlled and the bleeding will gradually be relieved. However, the exact time is related to the actual situation of the patient and the treatment plan, and cannot be generalized. If bleeding still occurs after the inflammation is controlled, it is necessary to consider whether other reproductive system diseases (e.g. endometriosis, cervical lesions) are present. Therefore, it is recommended that the patient should consult the doctor in time and be given targeted treatment by the doctor.
