Announcing “early”

sa

How taboo would it be to announce that I’m pregnant once I’ve gone to my 8 week scan? (assuming that the baby has a heartbeat and all is well). I’m a teacher and it’s getting harder to hide with the nausea and need for frequent bathroom breaks. I know that you’re “supposed to” wait until about 12 weeks to announce to everyone and that there’s still a risk of miscarriage.... has anyone announced around 8 weeks?
