If vaginal bleeding occurs suddenly during the non-menstrual period, clinically it is not necessary to stop the bleeding blindly, and the first thing to do is to find out the cause. If there is a history of normal sexual life, the first thing to rule out is that it is caused by pre-eclampsia, and blood can be drawn to check the blood HCG. if the possibility of pregnancy is ruled out, it is recommended that ultrasound be done to find out whether there are tumors in the uterine cavity, such as submucosal fibroid, or endometriosis, which can lead to the appearance of vaginal bleeding during non-menstrual periods. In case of coagulation disorders, thrombocytopenia can also lead to sudden onset of vaginal bleeding, so it is very important to identify the cause. Only after the cause is identified can different medications be given to treat the condition depending on the specific cause. If the bleeding is caused by submucous fibroids, oxytocin can be injected intramuscularly to make the uterus contract and reduce the amount of bleeding.
