Hey! I would agree-- say nothing, be dark. For now.
I think there is some sort of self-empowerment with doing what you just did. I think that's why you feel better. It will fade, though, when you start to second guess yourself. (Maybe you're there now.) And later you'll feel like you ruined everything. But you didn't. Stay consistent here for a while.
You and Bub! It's going to be so exciting and busy when the birth happens-- will you let us know within a week that it happened? What are you looking forward to most at that time?
