Hi! I am prone to BV also and it is miserable! A few years back, my doctor told me about some stuff called "Refresh" - you can buy it a Walmart for $14.00 and you get 4 vials. It balances the PH of the vagina and restores freshness - and you can use it anytime, every couple of days or so. It has helped me tremendously and I swear by it!! Try it! Good luck!
