I got STD tested and the results came back negative!!! But I still feel off

Amelia

So I got tested for all STDs and also bv and yeast however I still feel as if something is off because I am getting some discharge also along with odor and slight itchy ness, I’m not sure if there was a mistake at the lab but are there any tips other than probiotics? Any thing that could help with this stuff? Thanks 😊
