Morning-After Myths

The emergency contraceptive pill is not an abortifacient:

Part of the reason people get confused about emergency contraception and abortion is because lots of people are confused about the basic biology of pregnancy: specifically, that it doesn’t necessarily happen instantaneously and that sperm can live in the body for several days, during which time a woman can ovulate and an egg can potentially be fertilized and implant. Regular use of hormonal contraception prevents ovulation and the chance for fertilization; emergency contraception essentially works the same way except that it’s taken after sex, by which point ovulation may have already happened. But according to recent studies, there is no evidence that taking emergency contraception after ovulation and fertilization will stop the egg from implanting.
