It is hard to keep a pregnancy you wanted so bad a secret!

I don't think there is any "good" or "bad" time to tell your family or friends, its up to each individual person to decide whats best for them. Some people look at telling early, as they'd have a support system if something would happen. I told early with my very first pregnancy [ended in a m/c at 6 weeks], second one I waited til 8 weeks to tell immediate family and 12/13 weeks to tell friends. This pregnancy we're waiting til either 9 or 11 weeks.
