I need some advice...

Emmery

I am 6 weeks along. My husband and I planned to tell everyone after our first ultrasound at 9 weeks. He told his sister and I told my best friend who both promised they wouldn't say anything. Now here we are and they've both told at least a dozen people each. I'm afraid our families will find out from someone else instead of us and I don't want that. Should we tell them now?
