There are usually two types of abortions: one is abortion; the other is medication abortion. Abortion is a way to terminate a pregnancy through the manual use of an instrument. Abortion includes both normal abortion and painless abortion. Painless abortion is a way to terminate a pregnancy by using anesthetic. A medication abortion is usually a way to terminate a pregnancy by taking medication without mechanical surgery. Usually, the success rate of abortion is higher. There is a time limit for a medication abortion to be performed within 49 days of pregnancy, however, the success rate is relatively low. If a medical abortion is not successful, it usually requires an abortion. Both abortion and medication abortion can be harmful to women.
