Does plan b work 4 days later?

Yes, but diminishing: Studies have shown that women can still benefit from using Plan B as late as 4 days after unprotected sex. It's better than not using is you're worried about pregnancy. The sooner you take Plan B after unprotected intercourse, the better, but taking it is better than not! hope that helps!
