Maternity bleeding, mainly post-partum discharge, usually lasts for 4~6 weeks, but in some cases it lasts for 6~8 weeks to be completely clean. In general, postnatal discharge lasts 4~6 weeks, but if it is a cesarean section, then the postnatal discharge will last longer and may reach 6~8 weeks before it is completely clean. You need to pay attention to the local hygiene, insist on washing the area with water every day, and ensure that it is dry to prevent secondary infections from occurring. Before the discharge is not completely clean, it is forbidden to take a bath or have sex. If the discharge lasts for a long time and is accompanied by a distinct odor and heavy bleeding, it is considered abnormal and requires prompt medical attention.
