Yesterday, I had "unprotected sex" and I realize that since I'm on birth control no sex is really fully unprotected. But he did ejaculate inside of me, so it would have been unprotected if I wasn't on the pill. However, later that day I was supposed to take my birth control at 8 pm. but I forgot to take it until 6 am this morning. I took it right away, but now I'm really concerned with the possibility of this impregnating me. Will I be okay? Should I take the plan B pill just in case?
