Should be getting period very soon. lots of clear watery discharge. sometimes feel like it's leaking? not sure how normal that is. also some white too

Not normal.: As gross as it may sound, a copious, watery, (usually malodorous), vaginal discharge is because of a retained tampon. Because this is before your period, though, I'm a bit uncertain about what this could be. Usually yeast or bacterial infections create a thicker discharge that may have itching, odor, or pain with them. If there is no retained tampon and this persists, then see your Family Doc.
