The physiological period is usually around 3-5 days, and the whole menstrual cycle is around 28 days, but the specific period and duration will be different for each person with different physique, diet and environment. If the period is about ten days long or shorter than three days, you should be alert to the appearance of menstrual disorders and actively regulate the menstruation at this time. If the menstrual flow is relatively small, you can take Angelica Pills or Uggs White Phoenix Pills to promote the shedding of the endometrium. If the period is long, you should improve the ultrasound of the uterine appendages and the routine examination of the leucorrhoea in time to clarify the occurrence of fibroids and actively receive treatment such as myomectomy or excision to prevent the continuous aggravation of the condition, resulting in endometrial hemorrhage and even anemia and other adverse consequences.
