Do emergency contraceptive pills increase the risk of ectopic pregnancy (pregnancy outside the uterus)?
Emergency contraceptive pills (a.k.a. ECPs, “morning after pills” or “day after pills”) do not appear to increase either the absolute risk of ectopic pregnancy or the chance that a pregnancy following ECP use will be ectopic. Available data suggest that ECPs do not increase the likelihood that a subsequent pregnancy will be ectopic.
