An abortion, or termination, is ending a pregnancy so it does not result in the birth of a child. There are two types of abortion: medical, which usually involves taking two medications, normally 24 to 48 hours apart, to end an early pregnancy, and surgical, which involves a minor operation. Medical abortions can normally be accessed up to 10 weeks after your last period, while surgical abortions can usually be accessed up to 24 weeks after your last period. Medical and surgical abortions can generally only be carried out up to 24 weeks of pregnancy, but in exceptional circumstances, an abortion can take place after 24 weeks. Abortion is legal in Great Britain and can be accessed on the NHS.
