If the menstrual period is scanty and lasts for half a month, it is recommended to carry out the necessary examinations, such as ultrasound, to find out the condition of the endometrium and the condition of the uterine cavity. If the endometrium has uneven echogenicity or abnormal echogenicity in the uterine cavity, further hysteroscopy or endometrial curettage is recommended, and according to the results of the examination, the necessary treatment will be given. Blood HCG test can also be performed to find out whether the bleeding is caused by incomplete abortion due to pregnancy; gynecological examination can also be performed to find out whether there are polyps in the cervical canal, and whether polyps in the cervical canal are the cause of incessant menstruation. According to the different examination results, different treatment measures should be taken to stop the vaginal bleeding in time to avoid unnecessary harm or even delay of the condition.
