Possible pregnancy or early period ??

Last few days I have had really bad discharge to the stage I keep feeling wet! It’s clear & doesn’t smell etc but av never had this before , I got to the stage I thought i had ovulated later than normal but I still have it so it couldn’t have been that, last time I tested was Friday morning it was negative, could this be a sign of early pregnancy or is this a periods coming symptom & I just haven’t noticed it before ??
