How long can you wait to take a pill? Will it hurt taking it a week later after sex?
The highest chance for pregnancy occurs in the first three days after intercourse (sex) If you take Plan b within those three day or 72 hours you have a good chance of avoiding pregnancy. After the three days, if you are going to become pregnant, it is likely that you already are so Plan b really wouldnt be effective to prevent pregnancy. If you ARE already pregnant, adding all those hormones into a developing fetus can be harmful. Plan b wont stop a pregnancy that has already begun, it is only good for keeping a fertilized egg from implanting so after 72 hours, if it is going to occur, it already has. Not every sex encounter ends up in pregnancy though, so at this point you are better off just waiting and seeing if it has occured. From now on be sure that you use some form of birth control or just dont have intercourse. Condoms are easy to come by and most males know where to get them. If you end up not being pregnant, I would advise you to look into some form of birth control. Whether it be buying your own box of condoms and insist that your partner(s) use them or look into the Pill or Depo or another barrier method like a diaphragm. The Pill and Depo are best for spontaneity. Good luck to you!
