We told my family as soon as we found out (5 weeks) but we waited till we were about 13 weeks to tell everyone else
I waited til the day after my 13 NT scan. We lost a baby at 15 & 1/2 weeks so we wanted to make sure we were in the clear.
I told people at 13 weeks after the first ultrasound we got and you are past the first milestone for not having a miscarriage.
3 months is when I was told it's okay by my ob. just because the risk of a miscarriage. You gotta get past your safe zone.
We announced it at 9 weeks after my first ultrasound.
