I get reoccurring Bacteria vaginosis (BV). I had my 4th BV diagnosis last week. All occurring within the last 3 months. I always take metronizadole. The Obgyn doc who I last saw, prescribed me metronizadole vaginal gel. After the first day of taking it, I began having clumpy thick discolored discharge. After completing the 5 day prescription, I still have clumpy thick discolored discharge. Are you familiar with these symptoms and what do you think it causing it?
