Non-menstrual bleeding and also abdominal pain may be caused by ovulatory bleeding, ectopic pregnancy, cervicitis and pelvic inflammatory disease, uterine fibroids or other diseases, which can be treated according to different causes. 1. Ovulatory bleeding: After ovulation, the level of estrogen drops sharply, which may cause the surface layer of the endometrium to shed and bleeding to occur. In general, there is no bleeding or very little bleeding, but some people will have obvious bleeding symptoms. The bleeding may be accompanied by discomfort or vague pain or significant pain on one side of the lower abdomen, even involving the lumbosacral region and the inner femur. Occasionally, it can be observed and left untreated. For women with persistent ovulatory bleeding, oral estrogen or hemostatic drugs are needed to improve the symptoms after excluding other diseases. 2. ectopic pregnancy: the typical symptoms of ectopic pregnancy are menopause, abdominal pain and vaginal bleeding. If there is no contraception during sex and the symptoms of non-menstrual bleeding and also abdominal pain occur, it should be considered to be caused by ectopic pregnancy. Prompt medical attention and diagnosis can be confirmed by urine and blood HCG tests and vaginal ultrasound. In the acute stage with heavy bleeding, surgical treatment such as laparoscopic or open salpingo-oophorectomy should be performed as soon as possible; in mild cases, drug treatment can be chosen under close monitoring; 3. Acute cervicitis and pelvic inflammatory disease: symptoms such as increased vaginal discharge and abnormal vaginal bleeding, lumbar and abdominal pain may also occur. Antibiotic medication is mainly chosen. During the treatment period, sex is prohibited, high-risk sex is avoided in daily life, sexual hygiene is emphasized, and incorrect and irregular vaginal douching is avoided. 4. Uterine fibroids: typical symptoms include irregular bleeding during non-menstrual period and lower abdominal pain, which can be aggravated during menstruation. Drug therapy can be chosen to shrink the tumor, such as mifepristone, and another hemostatic drug can be chosen to improve the symptoms, such as tranexamic acid. If the fibroid causes excessive bleeding or infertility, surgical treatment such as open or laparoscopic myomectomy is recommended. Post-operative bed rest and regular review; 5. Other: In addition to the above diseases, other conditions such as endometritis, ovarian cyst torsion, gestational trophoblastic disease, gestational trophoblastic tumor, intrauterine device, etc., can also cause non-menstrual bleeding and also abdominal pain symptoms. If the symptoms persist or worsen, prompt medical attention should be sought to clarify the cause and provide reasonable treatment.
