wait a few days id say and if you really find out go see a doctor. you will know for sure. have unprotected sex even if you are on the pill can still get you pregnant. when u have sex not only are you risking pregnancy but also all those stds and i know its not something you wanna hear, or ur saying you know all this. i was on the pill and didnt make my bf use a condom, i didnt only get pregnant but i also got an std. thankfully it was one that with some antibiotics will go away and wouldnt harm the baby. so when u go n get a pregnancy test go get checked for stds as well.. i wish you the best and you have us all here at SUG if you need to talk dnt be afriad
