So my girl friend and I had sex I checked another web site to what that one thinks its saying most likely not pregnant but she has cramps I think its because of the rough sex like the site said so she didn't produce thy liquid allowing it to slide in her easily so it was rough causing some bruising and that's why I think she had cramps but she threw up I think it could be something she ate but it was in the morning when she puked she gained three pounds but has been eating a lot of junk food constantly but she has no cravings she won't get her period until march 8, 2008 but I can't wait and I'm only 15 or so I can't just go get a pregnancy test for her plus she lives far away . My question I'd she pregnant even though every syptoms has a second reason for occurring take the cramps because tough sex I'd there really a kid inside of her I pray not
