Pregnant?

Trying to decide if I should get my hopes up about a pregnancy. My boobs have been crazy sore. I think they look bigger too. My moods are crazy. But I'm not sick, I don't "feel" pregnant. I don't want to get my hopes up but part of me feels like I might be pregnant. I can't test for at least 2 weeks because I'm not even supposed to start my period till sept 6. Advice?
