My boyfriend did not penetrate me but he pressed his penis against my vagina. I don't know if he had pre-cum on it or not. The day after this happened, I got my period, and it was a normal cycle for me. I have been off of my period for two days now and feel extremely hungry and have noticed a bit of weight gain, along with moodiness and irritability. What does this mean for me? Is this hormones from my recent menstrual cycle or could I be pregnant? Would the fact that my period began right after this occurence nullify any chance of me being pregnant?
