Hello, I have been having just a little bit of mucus in my stool for weeks now. But for the last two days it a lot, its not attached to my stool it comes out during my bowel movement not attached. It is the size of a mans thumb nail and it is really thick and it feels more like raw chicken skin but thicker and its hard to tear it apart. I still have traces of mucus on my stool as well. I noticed that my stool is dark brown. Thank you.
