Part of mucus plug??? 27 weeks

I’ve had mucus when whipping here and there throughout this whole pregnancy however nothing at all like this.

I went to the bathroom and when I whipped it felt much different. The picture doesn’t really do justice to how big it actually was…it was a lot.

Then I whipped 2 or 3 more times afterwards and the paper was covered in slim each time instead of a big clump.

Should I be concerned?

I was also having new pains and discomfort when trying to go to sleep last night, not sure if that would be related.
