The causes of brown discharge during non-menstrual period may be ovulatory bleeding, side effects of emergency contraceptives, trichomoniasis, cervicitis, uterine fibroids, ectopic birth control ring, etc. It is recommended to clarify the causes and give reasonable treatment and handling. Common causes and treatments: I. Physiological causes: 1. Ovulatory bleeding: the level of estrogen drops during ovulation, the endometrium is shed, and the bleeding is manifested as brown discharge during non-menstrual periods when the amount of bleeding is small. Ovulatory bleeding generally occurs occasionally and the amount of bleeding is small, so it can be observed without treatment. For women with continuous ovulatory bleeding, oral estrogen or hemostatic drugs are needed after excluding other diseases. 2. Side effects of emergency contraceptives: After taking emergency contraceptives, the next menstrual cycle may be early, delayed, bleeding more or intermittent, i.e., non-menstrual brown discharge, if there is no other discomfort, observation is recommended; if the symptoms persist or worsen, medical treatment is needed. Pathological causes: 1. Trichomonas vaginalis: due to inflammatory stimulation, there can be bleeding spots accompanied by leucorrhea discharge, i.e. non-menstrual brown discharge, accompanied by pain during sexual intercourse and vaginal itching. It is mainly treated by oral antibiotics. 2. Cervicitis: Cervicitis is an inflammation of the mucous membrane of the vaginal part of the cervix and the cervical canal. The main symptoms are increased vaginal discharge, abnormal vaginal bleeding and brown discharge when the bleeding is small. Acute cervicitis is treated with antibiotics, such as cephalosporins or aminoglycosides. Hygienic habits and fixed sexual partners should be practiced in daily life. 3. Fibroids: Typical symptoms include brown vaginal discharge during non-menstrual period and even irregular bleeding. If the fibroid is small in size, it can be reduced by medication to improve the bleeding symptoms; if the fibroid is large in size and causes bleeding or infertility, surgery is recommended; 4. IUD ectopic: When the IUD is ectopic, irregular vaginal bleeding and increased discharge may occur, and there may be symptoms of lower back pain and brown discharge during non-menstrual period. The ectopic birth control ring can lead to unwanted pregnancy, so you need to go to the hospital as soon as possible to check and rule out abnormalities. 5. Other diseases: endometritis, cervical polyps, pre-eclampsia, ectopic pregnancy, ovarian cysts, gynecological malignancies and other diseases may also show symptoms of brown discharge during non-menstrual periods. If the symptoms persist or worsen, you need to go to the hospital in time to clarify the cause and treat the cause.
