"Booking in scan"

I recently had a miscarriage and received a  booking in letter for my 12-week scan that had been typed 3 days earlier - my miscarriage took place ten days before.

I’ve read previous accounts of this happening before, and obviously nothing has been learnt, and no attempts have been made for Early Pregnancy Problem Clinic and the booking centre to communicate with each other to avoid this happening.  

It might not sound like a big deal to some but receiving that letter and subsequently having to call the receptionist to cancel said appointment and tell them why has really set me back emotionally.
