Help! Yeast infection.

I’m positive it’s a yeast infection as I used to get them frequently but not so much anymore. It’s about day 4 now and I just can’t handle the itching and burning. I don’t have health insurance and I can’t afford a trip to the doctor. I’ve tried monostat before and had a horrible reaction to it so that’s a no go. Does anyone have any tips to kick this infection or relieve the symptoms?
