You can warm your abdomen with a warm water bag on the 2nd day of your period, take Yimoucao granules orally to promote uterine contraction and observe the discharge of menstrual blood. If the menstrual blood is discharged, it is mainly related to stagnation of qi and blood, if it is still not discharged, it is mainly related to low menstrual flow, insufficient qi and blood, menstrual disorders, endocrine disorders and other factors. At this time, we should pay attention to eating more animal offal, gum, fungus, brown sugar, wolfberry, red dates, red beans and other foods that replenish qi and blood, as well as reducing the number of late nights to make the period as stable as possible. If there is a long-term decrease in menstrual flow, it is necessary to improve the female hormone six tests in time to exclude endocrine disorders, and actively take oral medication such as Wuji Baifeng Pill, Aihu Nuangong Pill and Menstrual Blood Regulation Pill. If the period is gone on the 2nd day and you are of childbearing age without contraception, you should consider the possibility of pregnancy.
