Orange mucus in stool persisting?

My gut has been flaring and I’ve never experienced this before. Probably about 8 months ago, I started seeing orange/yellow mucus when I was to wipe my stool. I originally thought nothing of it. It’s continued very consistently every time I have gone to the restroom, and sometimes it is just when I wipe, others my actual stool is orange. Honestly, I don’t eat a lot of carrots or any orange foods, which was my first thought. I’ve had some pain (only at night) around my middle to lower right abdomen. The stool has sometimes had stringy portions in it that almost look like flayed rope? I’ve been to a gastroenterologist before, maybe two years ago, gotten a colonoscopy and endoscopy done and I had ulcers. I went for stomach pain which the ulcers caused and the doctor linked to ibuprofen. I haven’t had that same type of pain again, thank goodness. The type of stool hasn’t been very consistent. Sometimes its diarrhea, sometimes its constipation. The only consistent has been the orange/yellow mucus. I have no pain in my rectum unless I’m constipated. I’ve noticed lately my stool has also smelled very, very foul. I have not started any new medication. I would just like some help… should I be concerned? Is this a normal thing?
