hi, my boyfriend and I were having sex about two weeks ago and after he came (with a condom on) about 15 minutes later we were messing around and he put it in once half way before I stopped him, I aim on the contraceptive pill but as I was sick the week before I had forgotten to take it one day and that night as well, I took it as soon as I realised the next day. Is there a chance of me being pregnant?
