Exam worry

So I was in my Maths Paper 1 exam the other day, and I had a hair clip in my hair to keep it out of my face. Once my invigilator said the exam was over, I put my equipment into my blazer pocket and took my hair clip out. I held the clip in my hand, and he came to collect our paper and saw the clip. Now, this clip was shiny, like the screen of a phone, and I'm worried he thought I was using my phone. I obviously didn't have my phone with me. It was in my bag, but what if he thought it was?
My question is, what would happen if he really did think this? Would he have spoken to me about it, or will I have to find out on results day? I'm so scared that I'm gonna get disqualified.
