First trimester MTP refers to an abortion carried out during the first trimester of pregnancy (1-12 weeks). An abortion can be performed up to 13 weeks into a pregnancy. The doctor gives women who are less than 12 weeks pregnant prescription drugs. The abortion pill is another name for it. The two medications in the pills, Mifepristone and Misoprostol, allow the womb to expel the growing foetus. A surgical abortion is typically carried out when a medicinal abortion is unsuccessful.
