JenniwithanI.... we haven't told anyone except our immediate families, and one set of DH's cousins, who flat out asked about doing IVF. Dh and I had decided that we wouldn't tell anybody else, as for most of this journey we haven't known what we're doing, what to expect etc etc, and things have changed so much. We decided we would tell anyone who actually asks, but apart from that one cousin, no-one (e.g. work, friends etc) have asked - I think most people have more tack than putting others in a difficult position to ask tricky baby questions. I may have told people, but DH and I had this conversation early on (and then throughout) and he was against telling people, so I was happy with that.
I know that eventually when I do tell friends etc that they will be very annoyed that I didn't tell them, but it's me who's had this anguish (understatement there!!) and any of their problems absolutely pales in significance - it will be about me, not them. It's a little harsh, but I think we need to put ourselves first.
I've tried to get my DH to join and post on here, but he won't - he likes to ebay sightsee instead!! I just make sure that I'm always reading things out from here to him, and he seems happy to know what everyone's thoughts and experiences are.
