Help! Yeast Infection?

Hi everyone! First time user here. I really need help. I know everyone isn't really qualified, but I need help because I don't have access to a doctor. I've never had a yeast infection, but I'm afraid I have one now. If this is too TMI, tune out now. Here are a couple symptoms I'm having. Burning, itching, yellow/smelly discharge. Thanks everyone! (And sorry for the TMI post.)
