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.
While discharge from yeast infections, which is a common kind of vaginal infection, doesn't usually have an odor, other kinds of infections do. Bacterial vaginosis, the name for overgrowth of bacteria in the vagina, causes discharge that has a strong, fishy odor.
