Need testing!: If you have a sexually transmissable infection, you may have become re-infected if you had sex with an untreated partner. You need to see your dr who should do a complete pelvic exam, as well as std testing. Bacterial vaginosis can also give an odiferous vaginal discharge that may not be sexually transmitted but can be diagnosed through testing, and treated appropriately. Recurrences can occur.
