TMI Photo!!! Mucus plug??

Chantel
Hi ladies, I hate to be "one of those" ladies who posted a pic like this but I just really need advice from a private forum. My husband and I were just being intimate and after I went to the bathroom. When I wiped this was on the paper? Is this my mucus plug or a part of it?? I am only 31 weeks so I'm a little nervous and not sure what I should do. This is our first baby. Should I call the Dr? Thanks in advance!
