Give Me Your Wisdom

I have been fighting with my ph and stuff for over a week. I don't know if I'm not wearing enough cotton underwear or using the wrong wash, but every other wash I use gives me a crazy outcome, some being mild yeast infections and BV. I don't know what to do at this point, but even if I were to shower at this very moment the odor would still stick around and it's just....disgusting. Please, please PLEASE help. 😷😷😷
