Thick CM before period

Yazmin 🌺

My period is due on June 13. Since the day after ovulation my CM has been watery, and a whole lot. When I mean a lot it sometimes feel like I peed myself or like I started my period. Now today 2 days before I start my period during my morning pee when I whipped my CM was a lot but see through, slippery and thick. Does anyone know what this means?
