Abdominal pain and yellow mucus in the stool: Possible diverticulitis? Looking for experiences and opinions?

The problem is, I suddenly felt pain below my belly button and in my lower left abdomen. Two days later, I went to the hospital, where they took blood, performed an ultrasound, and conducted a urine test.

I had to stay in the hospital from February 2nd to February 3rd because they weren't sure what was wrong. Unfortunately, no one could tell me what was wrong with me, and after another ultrasound, I was discharged.

The pain persists, and today I noticed extremely yellow mucus in my stool. Based on my own research, I suspect diverticulitis.

There may be users here who work in this area and would like to take a look.

Note: I know that gutefrage is not medical advice, but I would like to get other opinions.
