Hello. BV doesn't itch. It's most known for a REALLY bad smell and thin, watery sometimes grey discharge. So, this doesn't sound like BV from what you say. It could still be a yeast infection even if it is different. I had one after taking antibiotics and it was weird. I had very little discharge with it and just the itching (which was bad enough--- that itching is ANNOYING). Anyway, it was a yeast infection but just a bit different than I'd ever had. So, you can always go to the doctor and be swabbed but I'd consider it either a yeast infection/fungal infection and if not, women do get dermatitis from unknown reasons in that area. good luck
