An abortion is the termination of a pregnancy before birth, resulting in the death of the embryo or fetus. There are two main types: a miscarriage which occurs naturally, and an induced abortion which is deliberate. In the UK, abortion is legal under 24 weeks if approved by two doctors. Common abortion methods include medical abortion using abortion pills for early pregnancies, and vacuum aspiration for pregnancies under 13 weeks. There are potential physical and psychological side effects of abortion including an increased risk of miscarriage, infertility, ectopic pregnancy, breast cancer, as well as mental health issues like depression, guilt, and trauma. Complications can also include uterine hemorrhage, infection, and in rare cases, death.
