I had unprotected sex a few weeks ago. About a week after that I started what I am hoping was my period. I am normally really regular, but it was a week early and fairly light (but more than spotting). To be on the safe side, I took a preg. test about 2 weeks after I had sex and it was negative. But, now I'm having really bad nausea and heart burn (so bad that its waking me up in the middle of the night).

What I'm wondering is if there is a possibility that I'm pregnant. I'm not looking for a lecture about having unprotected sex, I just need some advice!
