What happens if all the fleet enema (sodium bisphosphate) came out clear?

Impaction?: It's possible that you have an impaction so hard and stuck up there that even the Fleet enema (sodium bisphosphate) did not touch it and therefore the only thing that came back out was the enema itself. Otherwise, I would really expect your stool to be some shade of brown. I am wondering what the consistency of it was? Liquid? You may need to see your doctor for a specialist referral and other advanced options.
