I’ve never had this before!

So today is my predicated ovulation day, and all day I’ve been really wet down there, but when I would go check it looked like regular cm, well once I got out the shower and went to use the restroom, it was so thick, and so much, (I know this is tmi) but it looked like hubby came in me, and we haven’t had sex yet. I have NEVER had this much cm, these pictures don’t even do justice.. does anyone know if this means I am fertile? Or why there’s so much? Thanks in advance.
