I've made a post or two over the past month about issues with BV. I've heard that for some women their period causes it every month. I think I have this problem, because I finished my antibiotics like I was supposed to but the BV came right back after I had my period. I used a hydrogen peroxide douche and yogurt, which worked really well for me. I also started taking acidophilus pills. My doctor suggested those methods for recurring BV because he said antibiotics become less effective if you have to use them all the time. Will hydrogen peroxide become less effective over time too? If so, what other options do I have for taking care of the BV?
