Ive lost a pandora charm how can i find it?!?! I think its in my room...?

...but my room's a little messy.I have cleared the area it might be in though. I think it has fallen off the bracelet when the stand that i keep it on fell on the floor. I have quite a thick carpet and it hasnt been hoovered up. Im really worried cos it was quite expensive and my mum wants me to find it. Please just any random tips for me to find it or things that you do when you look for stuff. Thanks xx
