For the past few months I have noticed a very sour smell coming from my normal discharge and it is driving me nuts! I have no pain or itchiness and the smell comes and goes every few weeks. I had a papsmear done while the smell was absent and all of my results came back normal. I used a one-night yeast infection medicine and nothing changed. I even have been drinking cranberry juice every day because I heard it helps the urinary track (which may or may not be true). I feel embarrassed because I notice the smell through my dress pants and I am starting to feel desperate. I would appreciate any advice you may have for me, thank you!
