12 week scan next week!! Announcement ideas?

Samantha
Due Jan 10 '17 or roundabout. Starting to get really excited now. 
First scan on Wednesday coming! (12 week) I will be 12 + 1. 
Beginning to feel real now, still have no idea how I'm going to announce it to those that don't already know! 
Any ideas??
(I'm in the UK)
