The bleeding time of natural abortion usually lasts 1-2 weeks, if there are other abnormalities, the bleeding time will be prolonged: 1. No residual pregnancy material: If the embryonic tissue and residual decidual tissue are completely discharged during natural abortion, with the recovery of ovarian function and the level of estrogen and progesterone reaching a certain level, the endometrium will gradually repair and vaginal bleeding will stop, which usually takes 1-2 weeks; 2. If there is incomplete miscarriage or placenta or fetal membrane residue, the vaginal bleeding will be prolonged after miscarriage and may be longer than 2 weeks, if necessary, the uterus will need to be cleared to remove the residue and the bleeding will stop gradually; 3. If there is still a lot of vaginal bleeding and obvious abdominal pain 2 weeks after miscarriage, you need to consult a doctor in time to determine whether there are still residues in the uterine cavity through ultrasound examination and treat the problem under the guidance of the doctor.
