With all my losses I prefer to wait, I hate the conversation that comes if everyone knows and then you m/c..."oh, your not pregnant anymore".

There's a small group of bellybelly ladies on my FB that I usually tell but after the last loss before Christmas I'm not sure I will even be telling them if there is a next time, I'm just so sick of having to announce I've had yet another m/c.

I think announcing your pregnant at the same time you announce the birth is totally acceptable!

But that's just me, so I would say do it when ever you feel comfortable, there is no right or wrong time
