Many women experience vaginal bleeding during non-menstrual periods, usually accompanied by vaginal discharge in the form of leucorrhea, which appears brown. There are many causes for this condition, and commonly we can consider the following factors. Natural damage to the vagina: If a man or a woman moves too much during intercourse, the vagina may be damaged and bleeding may occur, and the blood flow will be mixed with the leucorrhea, making it brown. At this time, it is necessary to stop intercourse in time and not to continue intercourse for 1-3 days to give the body a recovery period and to move gently during the next intercourse to avoid damage again. Gynecological diseases: Many gynecological diseases can be accompanied by vaginal bleeding without abdominal pain. For example, vaginitis, the inflammation can cause redness and swelling on the surface of the organ, resulting in a small amount of bleeding, and endocrine disorders and luteal insufficiency can also cause a small amount of vaginal bleeding during ovulation without abdominal pain. There are many cases of vaginal bleeding, which should be judged according to the characteristics of the patient’s condition. Therefore, once the leukorrhea is found to be brown, even if there is no abdominal pain, it is necessary to go to the hospital in time to avoid delaying the diagnosis and treatment of the condition.
