So my boyfriend and I were messing around and he had been inserting his finger in me with dried/wiped off pre-*** on his hand. Is it possible that I could be pregnant? I am not on the pill and I am supposed to start my period today. I know it's just a waiting game, but I'd like to know one way or the other.. Apparently I need to wait a week to take a pregnancy test? I should know by then anyway if I were to have my period.
