Anyone else dying to tell people even though it's still so early?

I am almost starting to resent this stigma in our culture of waiting to announce pregnancy. The first few weeks of pregnancy can be such a scary time. Although I have told a few close girlfriends and a few family members, I just wish it was more acceptable to talk about it freely. I wish it was okay to just drop "yeah, I'm pregnant, and I'm so exhausted" in casual conversation. Why does it have to be such a big deal? And why do miscarriages have to be such a secret too? Why do we have to suffer through these things nearly alone?
