What could I have? Is this normal?

For a little bit now I’ve had theses issues where I could smell myself from just sitting down in the car while driving, it’s a fishy order and I also have seen a difference in discharge where is more clumpy and white then a sticky texture, and recently I got a rash that’s bumpy, red and itchy and it’s around my area down there, I have already set an appointment with doc but what could it be?
