like u said there is always a chance of pregnancy i would get the morning after pill ASAP it still will be affective but it won't be as affective as if you took it a few hrs after it happened. good luck!
well i just had that scare, you both should be a little more carefull next time, ever think about starting to take the pill??? Will also make you're periods much lighter and less painfull. Go to you're doctors and talk to him/her.
I say if you expect him to wear a condom, you should go on some form of birth control. He has no control over that condom, I don't think they're really that effective. So, definitely go get some birth control if you're not. I don't think there is much of a chance you're pregnant, but, if you're worried, go take a test.
