Mucas plug or something weird??TMI

So I noticed a small brownish red clot for lack of a better word in the toilet after peeing. It was smaller than a dime. I called L&D they told me to wear a liner and to come in if anything else happened. I have no spotting no cramping babies moving normally and normal colored discharge. I have no idea what it was it wasn't a blood clot maybe some off colored discharge or part of my mucus plug?? But i'm only 27 weeks so it shouldn't be my mucas plug right?
