We told my bro, SIL and mum at about 7 weeks. This was because they knew we were TTC (after a mmc) and I was staying with them. They would have guessed straight away with the ms and fatigue - plus I had an emergency scan due to spotting the day I was supposed to be travelling to visit them. We told the rest of the family after the scan at 12.5 weeks. Then we've just put our 20 week scan on facebook. Don't feel under any pressure to tell people early if it makes you feel uncomfortable. Likewise, if it's going to make life easier just telling a few close people then go for that. I was actually glad that I told my mum, she was very supportive and was very good not telling anyone!
