If there is blood in the toilet but no menstruation, it may be due to pre-eclampsia, ectopic pregnancy, vaginitis, cervicitis and other diseases, which need to be clarified and given medication. 1. The first thing you need to consider is whether or not you are pregnant. If you are pregnant, you should consider whether there is a pre-eclampsia or ectopic pregnancy. You can follow the doctor’s instructions to carry out ultrasound, human chorionic gonadotropin and other tests to clarify the situation, and then give birth control medication and surgical treatment as appropriate. 2. If the time for menstruation has passed but the menstruation has been delayed, and the possibility of pregnancy has been ruled out, then it is necessary to know the thickness of the uterine lining, the function of the ovaries, and to check whether there is vaginitis, cervicitis, endometritis, etc., which may cause abnormal vaginal bleeding. You can perform gynecological examination, sex hormones, ultrasound, vaginal secretion examination, and follow the doctor’s prescription medication. If this situation must be taken seriously, it is recommended to go to the hospital as soon as possible to identify the cause of the disease and take timely treatment or adjustment.
