hi its a change in the mucus inside your vagina that causes it and once you get it it has this thing of just re-occurring time after time so its either off to the doctors for more antibiotics or you can try the sea salt way you do this by taken sea salt warm baths and let the water get inside you. you can google bv and sea salt for more info and help if this works for you saves keep stuffing your body with antibiotics. do hope you find some this helps for your problem. good luck
