Re: Bacterial vaginosis - unsure of what to do next
Cranberry juice can be great to prevent most UTI's. Just be aware that it's only been found to help prevent e. coli UTI's. It doesn't seem to be effective with other types of UTI's or vaginal infections. So don't rely on cranberry as your only approach to your problem.
You said your PCP performed the vaginal swab. Did your GYN swab you too? Maybe you have more than one type of organism causing your symptoms and the initial test didn't pick up all of them. You should be asked to be swabbed again, by a GYN, since you still have symptoms.
