12 week rule

How many of you are choosing to wait until after the first trimester to share your news? We shared with immediate family but plan to keep our little miracle a secret from the rest of the world just in case. It's killing me not to tell everyone but with it being our first baby and M/C, I feel like, is so much more common now we're choosing to wait. Just curious as to who's doing the same or what your opinions are?
