5 days Post rhinoseptoplasty and turbinate reduction and this fell out of my nose? (Photos)

I have no idea what this is, but I woke up to most of it hanging out of my nose. I thought it was mucus from surgery, so I wiped it with Kleenex and this entire thing fell out of my nose. I'm totally freaking out. What is this? I know that I had to have Spreader grafts to fix my collapsing nose. I still have my internal stents in, and go in to get them removed Monday. Called my doctor, and he seems to think it is a stitch. It does not feel like a stitch. Please tell me my surgery is not ruined!
