Question for adult diagnosees

Hi all,

I'm an adult in England and I had my through-the-NHS assessment a few weeks ago where the psychologist confirmed to me I was autistic.

Since then though I haven't heard or received anything in the post about it either from the assessor or my Doctors so I was wondering how long this usually takes? From what I have read I am meant to be sent a report?

Thank you in advance for any answers
