Would this be bad?

I’m asking because I’m not sure if I have a yeast infection or not. I can’t make it to the doctor anytime soon, so I’m thinking of purchasing an OTC treatment.

I don’t have a whole lot of symptoms… but over the past week, my discharge has gotten thicker and it’s slightly yellow. And today I have much more discharge than normal. It doesn’t smell bad, and I’m not feeling itchy, but could this be a yeast infection?

(Before anyone says it, it’s absolutely not an STD. Completely impossible.)
