Stretchy clear discharge day before period! Pregnant?

Hi girls! 
I know this isn't the nicest topic but I was wondering if anyone knows what this means? I've had quite a bit of clear stretchy discharge today and tomorrow my period is due, it's the first period that I'm off the pill. Usually before my period I don't have any discharge at all or a little bit of white discharge, not like this though. I read somewhere it means you're pregnant?? Is that possible?
