Sounds pretty thrushy to me, it can feel like a uti sometimes and especially with the massive AB load. You need to make some major changes to your diet after that if you want to quickly get on top of it.

Loads of stuff in my thrush article, as well as the specific probiotics for womens vaginal health. All in the article.

Chuck out any wheat, sugar and get as much fruit and veg in as you can. Leafy greens your heart out. Coconut oil is antifungal. Replace your oils and take it orally. Keep up the probiotics but it will take time to reestablish the good flora which has no doubt been wiped out and struggling to reestablish.
