My boyfriend and I had sex on the 21st (when I began ovulating) and he came inside me. My period isn’t due until the 5th of next month. A few days after we had sex, I started getting BAD heartburn that would wake me up in the middle of the night for a few days. Now I’m getting nauseous and having slight poking cramps in my lower right pelvis. Also I’ve been peeing like every hour (doesnt smell or burn). Obviously im going to be taking a test if I miss my period, but I want some answers! COULD I possibly be pregnant? Help!
