For the past 2 weeks, I noticed a very foul (fish-like) smell coming from my vagina. For the first day or two, there was a slight white milky discharge, but it went away as abruptly as it started. It made me think of yeast infections from years ago. Since then, there is just the odor. I am post-menopausal, 62 years old. I had one sexual encounter with one man approximately 10 days prior to noticing the smell. It is quite offensive. Can it clear up on its own over time? Can I do anything to kill the smell?
