I'd Read That Applying Coconut Oil Onto Your Vagina Was

I'd read that applying coconut oil onto your vagina was good for you and practiced such for a few days only to now have what appears to be an infection. I have redness as a result of irritation, swelling, and a burning sensation when I urinate. I am not sexually active and last visited my local clinic for STD testing, four weeks ago, where I tested negative for all STD's and STI's. I do, however, experience reoccurring yeast infections. Other than Monistat, what would you recommend that I use to treat myself? Would olive oil be a good remedy for the soreness?
