USUALLY a fishy odor means some type of infection. However, there is somewhat of an odor during and after menstruation, for some women. Just monitor it over the next couple days. If it still seems to linger, then I would suggest you go to the doctor, or do some over-the-counter vaginal/yeast infection cream.
Fishy odors begin to develop in fish immediately after they are caught and killed, as bacteria on the surface break down the compound trimethylamine oxide into stinky trimethylamine. As long as the flesh is still firm and the skin is shiny rather than slimy, this fish is still fine to cook and eat.
