If the bleeding exceeds the amount of menstruation, it is necessary to go to the hospital for examination in time. It is possible that there are residues in the uterine cavity, and it is also possible that the uterus is poorly rejuvenated or the uterine cavity is infected after childbirth. If there is a small amount of bleeding and the malodex is pink, you can temporarily observe until 1 month later. If there is still red malodex, it is not normal and needs to be checked and treated in time.
