It is possible to have a clean medical abortion, and there is no necessary connection between a clean medical abortion and having a child. When taking a medical abortion, there are no contraindications to abortion, and the time to take the drug is within 49 days of menopause, the diameter of the gestational sac is less than 2cm, and the smaller the diameter of the gestational sac in the uterine cavity, the higher the success rate of abortion through drugs. If the time of menopause exceeds 49 days, or if the diameter of the gestational sac is greater than 2cm, and if the woman’s gastrointestinal reaction such as nausea and vomiting occurs after taking the drug, the drug cannot be completely absorbed, it will affect the effect of the drug abortion, and the drug abortion will be incomplete or even the drug abortion will fail. Therefore, when women take the drug abortion pill, they must take it in the regular hospital, and after taking it, they need to do ultrasound to review the effect of drug abortion.
