Chronic itchy vagina?

Before anyone says "see your gyno", I am working on it. I don't have health insurance and I'm waiting for a response for Medicaid.

So my vagina itches a lot. It only happens when I have my normal discharge. I don't have any abnormal discharge. Doesn't smell or look off. Itching stops when I go wash my area. I shower every other day so I'm not a dirty person. There are no bumps or any type of visible reactions. It's like I am allergic to my own discharge or something.

I've tried yeast infection medication (metrodinazole and Monostat) and it didn't work. What could it be and what over-the-counter medications can I try while I wait?
