Vaginal bleeding one month after miscarriage is recommended to go to the hospital for timely examination and ultrasound to see if there is residue in the uterine cavity. If the residue is embryonic or meconium tissue, the uterus should be cleared in a timely manner along with anti-inflammatory treatment. If the residue is simply blood in the uterine cavity or poor uterine regeneration, it can be treated with medications that promote uterine contraction, such as motherwort pellets. At the same time, we should pay attention to the vaginal discharge for odor, abdominal pain, and elevated blood count. If there are signs of infection, antibiotics should be applied to treat the inflammation to avoid pelvic inflammatory disease, and go to a regular and qualified hospital when choosing to have the uterus cleared.
