miscarriages, still birth questions

Okay ladies.. freak out moment! Let me start out by saying I had a miscarriage earlier this year at 6 weeks 2 days. People have always told me after the first trimester you're pretty much in the "safe zone". But I've been seeing all these posts about babies lost at 17 weeks, 23 weeks, 26 weeks and even 41 weeks with a stillborn.... it's really stressing me out! I already announced my pregnancy and I'm really worried about the fact that I did now. We've already seen our baby on ultrasound and heard the heartbeat, but it doesn't ease my mind because obviously these other mothers did too.. are the odds greater than the 1% chance we've been told??
