I missed my birth control for a week...?

The problem with birth control is that you really do have to take it on time or it won't work. There are plenty of women out there who claim to have gotten pregnant on birth control. Usually, this is because they missed a day. So, that really is not in your favor. However, if you don't know what happened, it's hard to know. There are a lot of reasons your bikini could have been untied...perhaps it simply came untied while making out. Or maybe you guys were fooling around but didn't go all the way...Don't freak out. Chances are you're fine. As far as throwing up goes, morning sickness doesn't happen that quickly after becoming pregnant. You could be sick from something else. If you are that concerned, see a doctor. It's a bit late for morning after pills (you have to be 18 to buy them anyway). Hopefully your periods are just screwed up from the pills. They should make you more regular, but anything is possible. Good luck!!
