I Have Struggled With BV For Years. I Am Now

I have struggled with BV for years. I am now 40 years of age and it seems as if the bv has worsen. The discharge and odor is terrible. The antibotics are no longer working. I eat Yogurt daily and take various probotics daily. The antibotics that I currently take are Boric Acid Suppositories, Clindamycin cream, Metronidazole and Tinidazole. I alternate from week to week. I am sick of the BV and my body has become immune to the antibotics. I work in an office environment of which people can smell me. What do I need to do.
