There are two types of cases: physiological and pathological; physiological cases can be left untreated, while pathological cases are mostly due to luteal insufficiency. 1. Physiological conditions: If each menstrual period is seven days early, and the menstrual cycle is not less than 21 days, and there are no uncomfortable symptoms, then it is a normal situation and does not require special treatment, but it just means that women’s menstrual cycle is shorter. 2. Luteal insufficiency: There will be follicle development and ovulation in every menstrual cycle, but insufficient secretion of progesterone in the luteal phase or premature luteal atrophy can be manifested as a shortened menstrual cycle, and can also be manifested as not easy to conceive or miscarriage in the early stage of pregnancy, etc. Estrogen such as estrone can be used for 5~7 consecutive days starting from the 5th day of menstruation, and progesterone can also be used for post ovulation treatment such as progesterone. There may be other reasons for menstruation seven days early, you should go to the hospital in time and do the relevant examination, in order to clarify the cause of the targeted treatment, do not take medication without authorization, in order to avoid delaying the condition.
