I have been having thick/chunky white discharge from my vaginal area. My doctor has tested me for HIV's, AIDS, yeast infections, bacterial inflections; and the tests all come back negative. This problem didn't start occurring until a few years ago; it started out mild with clear discharge, then it became more frequent and eventually the discharge and the area around my vaginal hole were white, and even sexual intercourse hurts now. I have stopped taking all forms of birth control and even am not sexually active now but my doctor still hasn't been able to stop this and I have also been given many medications over the past couple years to treat this and nothing works, seems to keep getting worse. Do you have any idea what could be going wrong with me
