Confused on chances of miscarriage. Maybe it differs from country to country?

I post a lot on the forums with polls and stuff because I'm freaking can't get over my fear of miscarriage. I'm so paranoid.

Well anyways I just had someone tell me you shouldn't annouce at 11-12 weeks because your still in the first trimester and you have a 20 percent chance of mistake. 20 percent?!?!? That's so high. Everything I've read you have a 15 percent chance if your younger than 30 but as time progresses it gets less and less.

By 11 weeks its 2 percent from literally everything I've looked at. And it's always less than 3 percent after hearing the heartbeat.

I live in California, USA. Maybe in America the studies are different? Just curious that's all :)
