wow thanks everyone. i'm looking into birth control right now...i guess i thought it would harm my body way more as opposed to taking plan b for only emergencies...
Don't worry it should still work. But like Laura said its an emergency contraceptive not regular birth control and it is only 85% effective so you still have a higher chance of pregnancy even taking it then you would on regular birth control. It can do terrible things to your body if taken too often and I'm sure that you want to have kids in the future so dont ruin your chances playing around with that stuff. Get on some type of birth control... when I was a teenager I really like the nuva ring.
Also, all Plan B does is prevent a baby from implanting, if the baby has already implanted it doesn't do a thing.
I do not think that you should have anything to worry about! Also if by some chance it did not work there is a slight risk to the baby but normally the babies that are born after Plan B not working are perfectly healthy! I also have to agree with LauraB78 you need to use a different form of birth control!
I agree look into some birth control if you do not want to get pregnant.
You should be fine. I don't think 40 minutes will make much of a difference. I would call the pharmacist to verify, but I think it should still work properly.
Plan B is NOT meant to be used as a FORM of birth control. It is an EMERGENCY CONTRACEPTIVE.
I strongly feel that if you do not wish to get pregnant, you should consider getting some other form of regular birth control.. ex: pill, IUD, SOMETHING.....
Good luck.
