Can septoplasty splints move?

I recently had a septoplasty done and was informed he had stitched splints in to my nose, now I was trying to remove the blood clots in my one nostril and it got stuck so I’m no longer sure if it was a blood clot or the splint that was stitched in to my nose. It was thick and black like the rest of my clots, but was the only one to get stuck. Is there a possibility I’ve moved the splint?
