Infection?

Makenzie
I can't tell if I have a vaginal infection or if this discharge is normal. And I hate to ask my doctor because he's horrible.. He never tests me for anything and it worries me. I can't tell if the smell of the discharge is normal or not. I'd ask someone else to smell it but I'd feel awkward.. What do I do? It's yellowish brown, it's not green or anything. But my outter labia burns.
