Can the morning after pill have an effect long term on uterus?
Untrue. All the morning-after pill consists of is a larger dose of the same hormones your body produces when pregnant, so it’s not much different than typical birth control pills. This serves to interrupt ovulation and thicken cervical mucus, ideally both keeping sperm out and egg from meeting with any potential sperm. There is no evidence that it would harm future fertility at all (ask anyone who’s gotten pregnant after taking it and hoping for the best). Moreover, it does not end a pregnancy or harm a developing pregnancy in any way either. If you’re taking it several times a cycle, then you may have issues with your periods and ovulation being thrown out of whack, but unless you’ve made a career out of gulping them and hoping for the best, you’d be just fine.
