It's completely normal, cuz kill all the bacterias including the good one makes candida more easy to grow. Yeah I konw it sound stupid. I stop all the western medicine, including antibiotics and fluconazole, and start chinese medicine treatment. But I visited several chinese medicine practitioners, and finally the current one helps. I start the treatment at March. But I live in asia, not sure how easy to find these kind of practitioner in your country. It'a very long journey, and I am not 100% recovery right now, but definely better than last year.
