Could this be nausea? im at work at i feel crap!?

It it could be pregnancy, but it's really early to tell. Your breasts hurting are a good sign of pregnancy, and so is the nausea. But I don't think you would wake up earlier. You become exhausted when your pregnant. You sleep a very long time, and even when you get plenty of sleep, are still tired. The cramping can be associated with pregnancy, too. If you start throwing up out of nowhere, feeling completely drained first thing in the morning, or get a severe hatred for the smell of chicken (not kidding) I would check it out with your doctor to see if you are pregnant. Also, keep track of your period. If you are never late and you don't get your period right on time, go get yourself checked out. If you're irregular, and your late, I would give it a week. Then if you don't get it, I would get checked out. Hope this helps.
