Overview

Emergency contraception (EC), or emergency postcoital contraception, refers to contraceptive measures that, if taken after sex, may prevent pregnancy. As its name implies, EC is intended for occasional use, when primary means of contraception fail. Since EC methods act before implantation, they are medically and legally considered forms of contraception. Some pro-life groups define pregnancy as beginning with fertilization, and consider EC to be an abortifacient.
