Hello! I'm a 21 year old female and I recently forgot my birth control for the last three days or so. I was with my boyfriend last Friday and we had some fun. He ejaculated on my chest and I quickly took his sperm off my chest and inside of me. Now I've been having hot flashes, cravings, mood swings, tender breasts, weird cramps, dizzyness for the last week and a half. Is it possible I might be pregnant? Thanks!
