Tummy problems (TMI) need advice...

So about two months ago I started feeling sick periodically. Maybe like 2-3 days out of the week it would last, then I’d be totally fine for a couple weeks. This keeps happening and yesterday it started up again, but with a vengeance. Like worse than usual.

My symptoms are stomach cramping and sometimes nausea. Pains in my lower stomach/intestinal area. And the most bothersome is my bowel movements. I know this is TMI but sometimes I’ll go like 5 times in a day within a couple hours, paired with intense stomach cramps. It’s normal though, not diarrhea. But then other times, especially yesterday and today, I feel like I have the urge to use the bathroom but only mucus comes out. It’s super uncomfortable and it worries me. I don’t know what it is.

Has this ever happened to anyone? I went to my naturopath and she gave me supplements and antibiotics. But it’s still happening.

Update: I did visit a doctor. As I mentioned, I was given antibiotics just in case, as a possible treatment for maybe some sort of bacteria or parasitic infection. I do have a history of bacterial infections, and I have an autoimmune disease.
