Pregnant??

Last week I had 6 people ask me if I am pregnant. And of course my mom had I dream that I was pregnant and the baby would be due in the fall.
I have been working out a lot lately to get off the 5 holiday pounds that I gained, but I am really paranoid now that might actually be pregnant. 
My stomach is sooo bloated, my boobs hurt, I am exhausted, and I have almost thrown up every time I worked out. These can all be pms symptoms mixed with the struggle to get back in shape.
My period is due next week and I can't think of anything else. I am so distracted. 
Does anyone have any advice or insight?
