Gas, burping gross....cramps

I am 7w5d and am having extreme gas and burps. It's so nasty. I can't stand burping. Anywho, has anyone had this cause cramps? This has been going on for days but about a half hour ago I got a painful cramp in my right side down at the bottom of my stomach. I went to the bathroom and was able to get some of the gas out, I'm at work, gross. Lol, and that seemed to help a little but now that I am sitting in my desk chair the cramp is back full speed ahead. :(
