Generally, lochia can be cleared within a week after a natural miscarriage occurs. The duration of lochia discharge during a natural miscarriage is also related to the length of pregnancy. If the miscarriage occurs during a later stage of pregnancy, there may be a longer period of vaginal bleeding because the endometrium is thicker, potentially requiring about ten days. Typically, it will clear within a week, and it should not last more than ten days at most. It is advised for women to undergo a medical examination at a hospital two weeks after a natural miscarriage, at which time the recovery of the uterus and any remaining tissues can be assessed. After such a miscarriage, it is important to rest, enhance nutrition, and abstain from intercourse for a month.
