Hello Rusfox: I have had the same thing recently. I have taken acidophilus daily: 2 (2 billion capsules daily) orally, and 3 inserted vaginally before sleep). The fishy smell went away after a few days. I am still doing it for awhile, until I feel it is gone for good. This alters the pH. I read that there is also something called aci-gel, available without prescription at pharmacies, but that it's expensive and messy. Good luck to you; I know it's not fun.
