well if you took a test and it came back negative then I don't think your pregnant and the plan b is to help you not get pregnant.. You never know though and about your period being late it could also be for many other reasons rather than pregnancy.. Good luck and keep us posted

1) you really should probaly try to take note of what you are taking!
2) 4 weeks late is not always a good thing, but if you are not shoinw any signs and have had neg test results I would say that its probally just the stress of you worrying.

If your 17 you can go on birthcontrol, I would sugest seeing your dr to go on it you dont want toe worry of getting pregnant.

All the best

Plan b is like an abortion pill if you have sex and could get pregnant or think you are pregnant or dont want to risk being pregnant and take it within 72 hours after sex it will mostlikely make sure you dont get pregnant.. But 4 weeks later? If you are pregnant that would have totally messed things up

Plan b is simply a couple of extra bcps. It is not an abortion pill at all, jessamyn is wrong in that.

And no, it would not have done any major damage if that is the case. But if you had negative pregnnacy test already, then you don't need to worry.

But as some other poster told you, the only one who can keep track of what you take is you. If you don't know what you are taking, or why, then you have a serious problem.
