Abnormal vaginal bleeding may be caused by pregnancy. For example, conditions such as miscarriage or ectopic pregnancy can lead to abnormal vaginal bleeding. Additionally, vaginal inflammation, cervicitis, endometritis, uterine fibroids, endometrial polyps, or submucosal fibroids may also cause abnormal vaginal bleeding. Emotional fluctuations or mental stress that disrupt the menstrual cycle can likewise result in abnormal vaginal bleeding.
