It is possible that bleeding during ovulation, irregular menstruation and endometritis may cause menstruation to come back five days apart.
1. During ovulation, the endometrium is partially shed due to changes in hormone levels. Bleeding during this period is small and transient, and can be cleared up by itself at the end of the ovulation period.
2. When the body has endocrine disorders, the lack of estrogen and progesterone can also cause the shedding of the endometrium and abnormal vaginal bleeding. Often changes in the environment, frequent late nights, tiredness, etc. may cause.
3. Inflammation of the endometrium, polyps and other conditions, irregular vaginal bleeding, the formation of menstrual dribbling and other phenomena.
For specific cases, it is necessary to do further examinations such as sex hormone six, ultrasound, etc., to clarify the cause of the disease and actively treat it.
