OK, so I have vaginal discharge that is stuck to the inside of the walls of my vagina. It doesn't come out but just clings there and I can scoop it out. I have been tested negative for all STIs including herpes, yeast, and Bacterial Infections. Nothing seems to be working. Is it possible to have some sort of candidas but still test negative for yeast? Is this a hormonal imbalance? Please help, this has been going on for almost a year!
