Anyone had a colonoscopy pre diagnosis?

My symptoms have been constant bloating and soft stool. GI doc has done an endoscopy and now my next step is a colonoscopy. Should I insist on a SIBO breath test before jumping to a colonoscopy or is this pretty standard procedure?

Test that I have done:

Endoscopy: no evidence of inflammation, ulcers or H pylori.

RUQ ultrasound- no significance. Surrounding organs look ok

Abdominal CT scan with contrast - revealed a ruptured ovarian cyst

Blood work - nothing abnormal

H pylori breath test - negative
