Yes, I have mucous discharge with my UC. However, I also have had bleeding, really bad abdominal pain and massive diarrhea...but right before I started getting UC I had bad constipation for about 3-4 weeks with some mucous with my BMs, which was unusual for me. It doesn't really sound like the same thing you're having though.
I don't have IBS, so I'm not sure what the symptoms are with that.
I agree with the above advice...go see the GI they referred you to or at least a family doctor and see what they think.
