Periods that are spotty for several days are a common manifestation of menstrual disorders. Diseases such as endometrial adhesions, cervical adhesions, endometritis, ovarian endocrine dysfunction, etc. may affect normal menstruation, resulting in low menstrual flow or poor menstrual discharge, which is manifested as spotty menstruation. Suffering from endometrial polyps, submucosal fibroids, multiple or large-sized interstitial myoblasts, or subplasma fibroids, and placement of a birth control ring in the uterine cavity may lead to abnormal bleeding in the uterine cavity, which manifests itself as the symptom of dribbling bleeding prior to the onset of the menstrual period. When symptoms appear, patients should go to the hospital in time for ultrasound examination of the uterus and ovaries to observe the presence of uterine fibroids, endometrial polyps, ovarian cysts, uterine adhesions and other organic diseases. If necessary, sex hormone six tests will be performed to clarify whether endocrine dysfunction exists. According to the results of the examination, the results will be analyzed, and treatment will be carried out after clarifying the specific causes.
