Is it legit? I’ve been struggling with this off and on for a couple years now and the doctors i’ve been to can’t seem to make it go away with antibiotics. Is there a natural cure that works? SERIOUS INQUIRIES ONLY PLEASE!!!

I’m 16 years old and was diagnosed with bacterial vaginosis. I took Flagyl(twice a day) for it for a week and the symptoms were gone for about two weeks and then it came back. I tried natural remedies and that didn’t seem to work so i was prescribed Flagyl again but instead took it for two weeks. During that time, the symptoms didn’t even improve and now that I am off they are getting worse again. I have never engaged in ANY sexual activity so I know it’s not an STD. I am addicted to sugar and often eat candy and pastries but when I am not eating that I am Always eating something healthy such as brown rice, lots of yogurt, fruit, etc. I also take acidophilus and folic acid twice a day. I rarely drink water. I know diet can have something to do with it so yea… also, can your laundry detergent cause bv? i am doing anything i can to prevent this (like using unscented soaps) but it just doesn’t seem to work so I’m thinking it might be something more serious than bv. With symptoms of a strong foul odor and excessive discharge I indescribably disgusting and self conscious at school, being that I am already obsessive compulsive about hygiene.
