BV or something else?

So recently I've had an upset in pH in my cooch, I'm assuming. I've had BV (bacterial vaginosis) once in the past but I don't remember it being like this. Idk if its my soap or detergent. I have a strange odor, not foul but definitely different. No itching or burning...the doc says I'm negative for UTI, BV, STDs, trich or yeast infection. So I think I want to start a "healthy vagina journey" if that makes any sense. I know plenty of water, daily vitamins, probiotics. What can I add to my regimen?
