Abdominal pain accompanied by bleeding one week after the abortion is due to contraction of the uterus caused by bleeding, resulting in abdominal pain. This is when there is residual tissue and residual pooling of blood, suggesting poor contraction of the uterus. When this occurs, go to the hospital as soon as possible to register with a gynecologist and have an ultrasound examination to determine whether there is residual tissue in the uterine cavity. If there is residual tissue, take oral medications to activate blood circulation and remove blood stasis, including anti-inflammatory medications. Usually, you can move around more to help the uterus contract and expel the residual tissue in the uterine cavity. If the uterine cavity is found to be normal during the follow-up ultrasound, oral anti-inflammatory and hemostatic medications can be taken to help the uterus return to its normal shape to avoid prolonged uterine contraction, which may cause prolonged bleeding and affect the health and future pregnancy.
