After the use of medication, a small amount of vaginal bleeding and the expulsion of the embryo may occur, but it is not accurate to determine whether the expulsion has been completed only by symptoms, and it is recommended to check by ultrasound and so on. Due to the different physiological structure of individuals and their sensitivity to medication, there may be some differences in the symptoms after the use of medication for abortion. However, a small amount of bleeding, expulsion of the embryo and placenta, etc. can usually be seen after taking the medication, but these manifestations do not mean that there is no residue in the uterus, so ultrasound or blood HCG measurement is needed after the medication abortion in order to clarify whether there is any residue in the uterine cavity. In case of incomplete abortion or continuation of pregnancy, intervention such as curettage is required. In addition, because medication abortion may lead to abnormal bleeding from the uterus and other structures, it is necessary to stay in the hospital for observation or hospitalization after medication abortion. Medication abortion must be performed under the assessment and supervision of a clinician, and its use by individuals is absolutely prohibited to avoid serious life-threatening accidents.
