Menstruation shows whether the blood clots are normal, according to the size and number of blood clots to identify performance. Menstruation, endometrium will show fragmented exfoliation, with menstrual blood discharged from the body, showing smaller blood clots, most of which belong to the normal phenomenon. But if the solid is coagulated into a black mass, it is considered abnormal performance, mainly due to menorrhagia or abnormal endometrial exfoliation. Because menorrhagia, discharge speed is too fast, too late for anticoagulation has been discharged; or large endometrial shedding, with fresh menstrual blood discharged from the body, at this time need to consider whether there are uterine fibroids, endometriosis, endometrial lesions and other diseases.
