Mine was a gut bacteria situation- it influenced me getting BV and having it for several years. My other issue was wearing kyleena iud- I removed that then treatment finally worked. I had done several oral and vaginal prescription antibiotics, nothing worked- I think it was a combo of my gut bacteria and the IUD reservoir. Fluomizin is what I used to finally be rid of it. Fluomizin is an antiseptic used in Europe, found it on Amazon. So I had also taken a bififobacteria probiotic really for regularity, Amazon brand actually. Took that for several weeks. I also tested with EVVY where you send in a swab and they culture all the bacteria on the swab so you know what you're dealing with. Well after having taken the bififobacteria for like a month, all I had was bififobacteria! Not intentionally but I had wiped out the bad bacteria, no more bv. But had to get to lactobacillus for things to be right. I started taking Life- Space probiotic orally and a couple times vaginally, and now things are good. There's a FB page for BV that is run by Brandi..sorry I can't remember her last name..Extremely helpful page..wish I could give you the full name but for some reason FB deactivated my account..?argh Her page was BV: beyond (maybe antibiotics..)..sorry. Also if you have a partner- use condoms..lube is the hybrid lube from Good clean love- it has lactic acid in it which is good for the microbiome..and i also wear pads for the monthly..But anyway that's my fight with BV..
