Clear discharge ?🤔 PLEASE WOULD LOVE SOME INPUT THX❤️

Today is my expected start of af I’m usually spot on or early by a day or two so we will wait it out today and tomorrow, but question is I have an increase in clear discharge kinda stretchy and no smell looks like slime water lol TMI I know I don’t remember ever getting that before period it’s usually a white thick discharge I do get? Any thoughts ? Could it indicate sign of pregnancy or is it normal?
