There are still residuals one month after the medicated abortion, indicating that the abortion was not successful and caused by the failure of the medicated abortion. The probability that a medicated abortion will be clean is about 80%, and if the gestational sac is too large or the patient is not sensitive to the medication, and if the uterus is not contracting well, it can lead to residuals inside the uterine cavity. The longer the residual time, the greater the risk of infection and bleeding. If the bleeding has been going on for a month, the uterus will have to be cleared and antibiotics will be given to prevent infection. Medications to promote uterine contractions are also needed. In cases where an infection has already occurred, it is best to consider hospitalization. During the period of treatment, it is necessary to pay attention to strengthening nutrition and physical fitness, as well as to prevent infection and vaginal inflammation.
