I am taking Nortrel 1/35 and this month I missed my first two pills. But I read the instructions and took the two missed pills right away and exactly as it told me to. My boyfriend and I have unprotected sex and then once he gets close to finishing he pulls out and puts a condom on. Then we get back to it. What are the negatives on doing that? And also yesterday we had sex and he came a little bit in me without a condom. It was two days before I was on my "sugar" pills. Please, does anyone know the chances of me being pregnant?
