Keeping things quiet

Gia
I'm trying to figure out how I want to handle this ttc/pregnancy. Our first baby took three years to conceive and I was very open about trying and it got frustrating when we weren't getting pregnant. I'm hoping this time it won't take as long since my body has been through it already. Plus I'm 34. This will be our second and last baby and I think I want things more private just between me and my husband. 
How have you all handled telling family and friends when ttc and once pregnant?
I'm thinking of not saying anything until I'm actually pregnant and only then to immediate family. And not announcing anything more publicly until much later (unless I'm showing). Did anyone have family who were upset you kept things so quiet?
