Sex education is the best in the US. That's why Business Insider debunked several contraceptive myths.
The first myth they debunked is the belief that you can't get pregnant having sex on your period.
Another is the idea that you can't get pregnant if your partner doesn't orgasm inside of you.
The myth that the morning after pill only works the morning after sex is false.
It works up to 72 hours after unprotected intercourse.
