I am dealing with this same thing right now. It is a pain (and painful!). On top of that, I have GERD. It seems like the reflux disease only makes the nausea and bloating and gas pressure ten times worse. I tried taking some Gas-X, but that didn't seem to help at all.
It might be gross, but honestly, I just let myself burp it all up. As they say, it's better out than in! My boyfriend thinks it's hilarious; normally I would be embarrassed, but I have an excuse--I'm pregnant!
