TMI post. Part of mucus plug?

I had a check today at 38w1d and my baby is at a +1 maybe +2 station but my doctor couldn't feel my cervix well because it was behind her head. He said maybe 1-1.5cm dialated. I got home from the doctor, had a very upset stomach and this was on the paper when I wiped. Does it look like part of the mucus plug?
