When To Announce

Courtney
FTM here! I was just wondering when other moms were announcing. Is 12 weeks a good time or should we wait until 13? So far everything's been great (except the extreme nausea!) we had an ultrasound at 7wks exactly and baby was measuring 7wks 4days with a strong heart beat! I've already made the picture we're using for the annoucement, just haven't actually officially announced it! Thanks!
