Vague pain in the abdomen and blood in the leukorrhea are mainly considered to be related to abnormal pregnancy, gynecological inflammation and cervical masses. Patients should go to the hospital for examination such as hysteroscopic ultrasound to clarify the cause. Common causes and treatment 1, abnormal pregnancy: such as pre-eclampsia, if the patient is in a state of pregnancy at this time, or has recently had sex without contraception, the symptoms of vague pain in the small abdomen and blood in the leukorrhea may be caused by pre-eclampsia. As the gestational sac breaks away from the uterine wall, the capillaries of the endometrium are broken, which in turn causes abdominal pain, bleeding and other symptoms. In this case, immediate medical attention should be sought and depending on the status of the embryo, either fertility treatment or termination of pregnancy should be performed. In addition, ectopic pregnancy can also cause the patient to have this symptom, which should be treated in time to avoid rupture of the gestational sac causing hemorrhage; 2. Gynecological inflammation: due to pelvic inflammatory disease, cervicitis, cystitis, etc., the patient can have abdominal pain, abdominal cramps, increased leucorrhea, menstrual disorders and other symptoms due to the invasion of pathogens and repeated stimulation, which cause inflammation and the formation of adhesions and scarring.

The disease is mainly treated through medication, and if the symptoms are serious, surgical treatment is required; 3. Gynecological tumors: cervical cancer, pelvic masses, etc. due to the invasion of blood vessels and nerves by local masses, resulting in abdominal pain and vaginal bloody discharge, it is recommended to consult a doctor in time and take targeted treatment according to the cause.
