It is often the case that brown blood comes out when the menstrual flow is low. Why is the menstrual blood volume so small? In the past, it was endometrial tuberculosis. The second one was endometritis, and dilation and curettage, which caused the uterus to become swollen. The endometrium is extremely thin, and there is another problem that is actually an endocrine problem. The endometrium is not stimulated by a very good proportion of estrogen and progesterone.
