Looking for treatment for Vaginal Candida?

I have strong itch "there" in vaginal area I assume it candida because I was on antibiotics for few months. Pops for all sexually transmitted diseases are negative. I am looking for natural ways to treat this disease. I am looking for the right probiotics and supplements (maybe with oregano oil ?) Please share your experience if you ever had the same or similar problem and how did you treat it?
