Recommendation on vaginal probiotics

TMI but I’ve recently noticed an “odor” coming from downstairs and I had it checked/tested for BV, yeast, etc. my results all came back normal. The smell is still there and it bothers me. I don’t douche or use soap. Does anyone recommend a vaginal probiotic that helps with smell? I’ve never taken one before so I am also weary/concerned if it’ll disrupt my birth control since it’s dealing with hormones.
