What doctor to go to?

I have had UTI’s before and this is not one of them. Instead of discomfort it’s burning bad “down there”. It’s so painful i can’t sit in my class without wanting to cry. It burns when I pee too. I thought it was a UTI so i took AZO and it didn’t help at all. Then moved on to thinking it was a yeast infection and used monostat but that somehow made things way way worse. It is mainly the vaginal opening where it burns the most. Help?? Do I go to an urgent care? Or do I need to get into an OBGYN? My problem is that it can’t wait... way too much pain
