Don't know what's going on..?

For the past few days/weekish I've been really itchy down there. So bad that I've had to go nude when sleeping and whenever I can pretty much and I've NEVER done that. I'm almost certain it's a yeast infection, but I know the discharge for that is usually like cottage cheese and mine isn't like that. It's not chunky at all, more slimey. But there has been a lot of it.

I'm sure the cause of it is the constant sweating that happens down there. I can't prevent it because I live in an extremely hot state with no AC and a hot box for a car.

I just want to make sure it doesn't sound like more than a yeast infection. I'm going to see my OBGYN soon but I just need some ease of mind now.
