We didn't find out till I was 6 weeks so told my mum straight away but then waited till twelve weeks to tell the rest of the immidiate family so the inlaws and my sister and brother. Husband told his boss at about 13 weeks so he could attend the appointments with me, and I told three close friends but other than that we haven't told other people. We aren't making any announcements on FB, so have only told people we trust not to post anything without thinking. We have a reunion party next weekend and non of them know apart from one we aren't hiding it but if they don't notice then I won't be shouting it out to them.
