Symptom help!

I have confirmed adeno and suspected endo (no laparoscopic surgery yet). I’m pretty used to the array of symptoms including fluctuating bowel issues from loose to hard to pass.

But I have had diarrhoea now for 3 weeks. Had an array of bloods and stool labs and all were normal with nothing explaining the situation. Strange and annoying. But I’m now getting worried. I have another doc appointment next week.

Are there others with similar experiences? Is it ‘just and endo/adeno’ thing? Or is it possible something else is going on? What did you do? What other tests could I request? (I’m in Aotearoa / New Zealand
