On the third day of my period i was messing around with someone and he put it in me a few times without a condom. He didn't ejaculate inside me. I also had a tampon in (very unsafe i know) i have a normal (if not longer than usual) cycle and yesterday was meant to be the start of my ovulation. i have been feeling some nausea and been slightly gassy. this is unsual for me. am i pregnant?
