Part of mucus plug or no?

Larissa
This has been a rough pregnancy. Contractions, spotting and started dilating yesterday. This morning when I went to the bathroom there was a snot looking thing in the toilet paper. Could it be part of the mucus plug, or something else? I'm 25 weeks. I did take a picture, but figured I wouldn't post it unless someone asked to see since it's not the most pleasant thing in the world.
