Help!!

I've only told a handful of people I'm pregnant. But I want to tell my whole family. I'm literally only 6 1/2 weeks though. I haven't even heard the heartbeat so how do I patently wait to tell everyone?? lol 😅

I'm partly worried because I don't want to have to turn around and say I miscarried right after but I also don't want word to get out before I tell people.
