CM - sorry maybe TMI

So I'm between 3-5 days late on my period. I've been late before. But the last week and a half I've been so tired and can't snap out of it. The thing that has me a bit confused is my CM. yesterday and a couple days before it's been really watery to where my underwear are wet. And yesterday I found clear sticky CM and I don't think this has happened around my period unless I'm already bleeding. What could it be? I've read a lot but want to know what you think.
