I think it is probably normal at this point. I would give it some time. If you google loop ileo images you will see that it has 2 ends. It goes up and it goes down, things can pass through. We all have some discharge, and you're soon after surgery. I'd give it some time. When you follow up, ask! You're only a few weeks to recconnect
It's not easy with the loop. it wasn't for me anyway. I know some people have a better experience, and I hope yours is, but the loop was tough for me, for many reasons. When do you follow up with your surgeon?
