Ok so Saturday, June 15th I had sex with a guy I've been talking to. It was unpertected. We were both drinking at a party before it happened. He told me he didn't cum in me, but I have heard that guys can't feel pre-cum. The next day I felt fine, and then all on a sudden I had pain in my lower stomach. Didn't think much of it, it almost felt like cramps but my period isn't due till July 2nd. Then Monday my stomach was killing me. I was constanly having to go to the bath room (not to pee... TMI I know). Then today I have been super tired so I took a nap and when I woke up I felt kinda sick to my stomach, and before I throw up I usually get a lot of spit in my mouth, but nothing happened, and now I'm feeling kinda dizzy. Is there any chance that I might be pregnant? My mom told me she had no symptoms when she was pregnant with me or my little brother until a couple months after conception... But I've read all women experience different symptoms sooner than others. Any advice?
