A member asked:

Would plan b work if taken on the 4th day after unprotected sex?

Maybe: It is best to start emergency contraception as soon as possible after unprotected sex. If started within 72 hours, it is highly effective. It may still work if started later and it will not harm the baby if you do get pregnant.
