Early menstruation with low black volume is mainly due to the phenomenon of early bleeding caused by insufficient progesterone in the body. Some women have bleeding right after ovulation, even up to a week or more, and this phenomenon is related to endocrine disorders, and then to high mental tension and stress. It is best to use menstrual regulating drugs, such as Wuji Baifeng Pills, which can effectively improve the phenomenon, and diet should also pay attention to minimize the consumption of cold, spicy and stimulating foods. During the period of medication, sexual intercourse is prohibited, and the vulva should be kept dry and clean to avoid bacterial and viral infections.
