I think it's kind of expected, as we just got married last month. Everyone kept asking about our 'busy' honeymoon!!
SIL (who is also pretty much my best friend) keeps nagging this month for a niece or nephew, so she knows we are. Both mums have been nagging for ages so they'll expect it.
Still I think it will be a lovely surprise all round when(if) we do announce it, although I'm hoping to wait til everything's a-okd before we told anyone. Just in case.
I do, however, want to tell the entire world that we're ttc. I can't even walk around the shops without feeling conspicuous cos I've started looking at baby stuff with googly eyes. I've taken to shopping in other towns so I can have a guilt-free browse!!
