Announcement ideas?

Erin

My husband and I have agreed to announce on my sons christening day in 2 weeks time when I will be 12 weeks. We plan to do it after the church when everyone is back at the venue for food and drinks but unsure what to do as dont really want to do a speech. Also my 12 week scan is the next day ( you cant reschedule to earlier in the UK) I had a scan at 7 weeks and saw a heartbeat, would you still go ahead?
