Okay so me and my boyfriend desided to go ahead and have sex. For the first time. Well it kinda hurt but I've been told about that. I REALLY like it, so we had it again the next 4 days. I know it's bad. But then we had it the day before my period started and he cummed 3 or 4 times INSIDE me. And that was a few weeks ago, now I'm getting sick to my stomach, getting really bad headaches and body aches. Could I possibly be pregnant??
