A brief background...I was diagnosed with IBS four years ago. It comes and goes, I have good days and bad days of course. In the past I've had a small, tiny speck of blood maybe 3 times tops. But this morning, I went to the bathroom and noticed more than I've ever seen. It was in mucus and a little in my stool. The past few days I've had allot of mucus in my stool, more than usual. I have mucus most of the time when I have a bowel movement. Should I be concerned?
