Your lady parts have a very sensitive pH balance. Many things from sex to what you eat can disrupt the balance. Some odors are merely temporary. But if there is a yeasty or fishy scent in addition to a discharge, it's time to see your doctor because it could be a marker of a larger problem like a yeast infection or worse. How do you prevent unwanted odor down there? First start by switching your underwear to cotton, then consider your body wash. You want to use a mild soap in such a sensitive area. On-the-go use wipes to keep the area bacteria and odor-free.
