Upper Abdomen Pain and Bloating

This is my second pregnancy. My first pregnancy was a breeze and didn't have the following. I was nauseous but now that has been replaced with being bloated and upper abdomen pain in the last couple of days. Like in between my belly button and ribs. Is this just gas?

I go to my OB on Tuesday but my gosh this is uncomfortable. Any advice on how to help alleviate it would be greatly appreciated.
