Clinically, if the menstruation is not cleared for more than nine days, it is an abnormal condition. It is recommended to do gynecological examination to find out whether there are superfluous organisms in the cervix, whether the local area is smooth, whether there are abnormal bleeding spots, and if necessary, to do screening for cervical cancer. In addition, clinical examination of blood routine is needed to know whether the platelets are normal. Ultrasound examination is also needed to know whether there are organic lesions in the uterus and whether there is abnormal thickening of the endometrium. If menstruation is incomplete and the endometrium is abnormally thickened, it is recommended to perform segmental scraping and send the scraped tissue for pathological examination, and then give clinical treatment according to the results. In case of incomplete menstruation due to fibroids, it is recommended that intramuscular oxytocin be injected to induce contraction of the uterus and closure of the blood sinuses, so that the menstruation will be cleared.
