CM egg white and stretchy 2 days late?

Hi, so today I feel bloated and some what crampy-ish, pretty moody. I went to the restroom and upon wiping I had LOTS of clear, stretchy, thick CM. I've never had enough to come out upon wiping and I've never seen so much of it. Glow said my fertile days were over with yesterday. Any idea what is going on? I checked my CM during this past week because it said I was fertile but it was mostly just creamy. Any insights would be appreciated.
