It is best to choose the right abortion method according to the condition and size of one’s gestational sac, including the duration of pregnancy, and there is no one surgical method that is best. If the gestational sac is around 1cm and less than 2cm, you can consider a medication abortion, although the success rate of medication abortion is 60% and the bleeding time may be slightly longer. If you do not want the bleeding to be long and do not want to take the chance of failure, you can have an abortion. It is recommended to choose painless abortion and abortion under ultrasound monitoring, so that no pain will be felt during the procedure and the procedure will be performed under ultrasound monitoring, which will reduce the chances of unsuccessful abortion. Regardless of the method of abortion, it is important to review the ultrasound after 10 days to ensure that the uterine cavity is in a normal shape to avoid thinning of the lining or residue.
