I have a strong odor coming from inside my vagina. It's not fishy like you would find with a bacterial infection, and I have been to the doctor and she said there were no abnormalities nor infections. I don't have the usual yeast infection symptoms of itching, disharge, etc. either. It's just this strong odor that's not pleasant. It's almost like a nasty old blood smell, which intensifies after intercourse. Can anyone tell me what the cause may be and how to get rid of it?
