Abortion drugs is a delicate and moral discussion which must be handled carefully. It is important to state that any form of abortion can ONLY be carried out by a medical professional, in a professional medical environment i.e a hospital or medical surgery (or at least issued in such).
There are several different types of abortion methods available, depending on how far along in your pregnancy you are.
The Abortion Pill, i.e. Medical Abortion, can only be taken up until the 9th week of pregnancy - meaning the first two months. The medical term for this drug is 'mifepristone,' which works by breaking down the lining of the uterus. This results in the termination of the fetus. This drug can only be administered by a medical professional.
After your 9th week of pregnancy, it is still possible to use the Abortion Pill, however, the risk of complications will increase sharply and you may need to stay close to a medical building in order to seek professional help. Taking the abortion pill later than 9 weeks into your pregnancy is generally ill advised.
