I was wondering whether a plan b pill has an expiration date. If I acquired it the pill a week before I used it. Did it lose its full effectiveness? Or am I still covered? I took the pill about 5 hours after intercourse.
Plan B, like all medication, will have an expiration date noted somewhere on the box it came in. And usually, when you get drugs from a pharmacy, those dates will be at least a few months away. If you still have the box, you can check the date, but even if you don't, it's fairly unlikely that the pharmacy gave you a drug that was about to expire within the next couple of days.

Given that you took it so soon after sex, there's a very good chance it was effective. Depending on what source you look at, Plan B (emergency contraception) is between 75% and 89% effective - since you did take it as soon as possible, you can assume you're very close to, or at, that 89% effectiveness rate.
It's always a good idea to take a pregnancy test after using EC though, so you can do that about two weeks after your risk.
