Don't know when to announce

I'm 10 weeks exactly today and I'm super excited to announce. I've already decided on how I want to do it but I can't decide when I want to. I was originally thinking 12 weeks and my husband definitely wants to do it at 12 weeks. But I'm just so paranoid that something could go wrong. In April I announced my last pregnancy as soon as I found out and then I ended up miscarrying in May. It wasn't fun having to tell people the bad news and I don't want it to happen twice in a row. When did you ladies announce and am I just being ridiculous?
