TMI!!!!: Herpes outbreak?

I'm planning on going to visit my OB on Monday and I'm trying to be less scared then I already am. I've been feeling swollen for the past few days and like my vagina hurts. There are small white patches inside and it looks inflamed and bloody inside my vagina. My discharge has been clear and watery but in large amounts. There are no foul smells. Does anyone know what it could be?
