Usually, it is recommended to rest for about 1 month after miscarriage in the third month of pregnancy, and for people who are physically weaker, the rest time should be extended appropriately, and the specific rest time is related to the individual state. As the embryo has a certain size in the third month of pregnancy, abortion needs to be induced at this time, which may result in residual tissue in the uterine cavity due to incomplete abortion, incomplete suction, etc., and may lead to uterine infection causing hemorrhage and other adverse consequences. Therefore, after the abortion in the 3rd trimester, it is often necessary to perform a uterine scavenging operation to expel the residues in the uterine cavity. This scraping operation will damage the mucous membrane of the uterus, which may lead to prolonged bleeding, increased bleeding, and accompanied by symptoms of abdominal pain. Therefore, it usually takes 1 month for the body to recuperate to restore the normal body condition. In addition, the specific rest time after miscarriage can be determined by taking into account the woman’s individual physical condition and the recovery of each organ. After miscarriage, you should pay attention to rest, try not to engage in heavy physical labor, pay attention to keep warm and avoid getting cold. Observe the vaginal bleeding, if the bleeding is abnormal, you need to seek medical examination and treatment in time. Eat reasonably and pay attention to personal cleanliness and hygiene to avoid infection.
