Advice please

Hello I'm on ortho tri cycles lo bc and have missed a few and haven't doubled up like I was supposed to. Af is supposed to visit me in about 9 days. It's very regular. My fiancé used the withdrawal method only and during the time I missed pills we had sex but he withdraw. And im now having symptoms of cramps in lower abdomen stuffy nose and sore breast and a lot of white creamy disharge. I was wondering if it was possible I could be pregnant?
