Help.

I'm 12 weeks and a couple days pregnant and I feel like I've swallowed a ballon and it's being inflated from the inside. My stomach has an uncomfortable amount of bloating? I can't suck in or extend my stomach at all. I've been drinking TONS of water and eating right and everything. I just am so uncomfortable therefore I'm irritable and I keep snapping at my poor husband. Any suggestions, tips, been there done that kind of situations?????
