Bloating or teeny tiny baby bump?

Amanda • Elementary school teacher married to my best friend 7/12/14. We love the outdoors--especially hunting & fishing.
This is my first pregnancy, and I feel like I've already gained weight at only 6 weeks. I'm constantly starving, but the scale goes up and down each day and I've pretty much maintained my prepregnancy weight. I just FEEL fatter and like my belly pokes out a little more? Could this just be bloat?
