Is it possible to menstruate for 20 days after childbirth?

20 days postpartum generally do not come menstruation.

Menstruation is the formation of endometrial periodic shedding bleeding, postpartum ovarian function may be restored in 20 days, but the uterus needs about 42 days to basically return to the pre-pregnancy state, during this period domestic demand can not be affected by ovarian hormones and shedding, so there is no possibility of pregnancy again
