Lots of cm?!

Al

Tmi but I was just in my bed without undies on after just waking up and there was a small spot of wetness. So I'm like oh shit am I leaking?! So I move and sit up and sit there for a few minutes and get up and there's a decent sized spot of wetness with a little white cm in it.

Am I just experiencing a lot of cm right now or is this an indicator of something? I'm 35 weeks!
