Reasons for throat swab to be late?

Hi,
Yes a paranoid question, I got a throat swab almost 48 hours ago and it’s still not at the DR’s yet. Any idea why?
I did have tonsil stones, could it be it’s late as the swab has grown some weird unknown bacteria? I’m paranoid it’s something bad and they are trying to figure out what it is! Im over reacting I know, but I suffer health anxiety – would tonsil stones grow something on a throat swab? I got it initially as I’d had a sore throat for a week yet the Dr couldn’t see anything that would/could explain the sore throat – my throat is no longer sore but I’m still paranoid.

Thanks!
