Gassy and Yellow Diarrhea

For a week and 3 days I've been very gassy and you can actually feel it in my case. You know that feeling you get when your stomach roars when it's hungry? Well I've been feeling this way the whole time so basically I can feel the chemicals bubbling or whatever and it's VERY annoying. On occasions, I'd feel like throwing up but not to the extent that I"ll actually do it and I never have in this issue. Sometimes for long periods of time I'll feel fine to maybe a few hours but it'll always come back. The weird thing about this is that this has never once caused me to lose my appetite or make me throw my food back up. Starting yesterday morning I have started having yellow diarrhea. I have had that color before a few years ago back when I was constipated. The advice nurse on the phone said it was fine and here I am now. However, at the time, it really, really hurt but this one doesn't. I just always feel gassy to a point where I burp, gas, sometimes feel the need to throw up when I don't, and have yellow diarrhea. I want to go in for this sense I have researched about yellow stool and it said that it usually means infection or something in relevance to that. May I have some suggestions as to what my problem may be, cause I most certaintly don't. Thank you.
