Today was the first OB visit! There was much anxiety, and I'll be honest, it sucks to be a doctor in this situation, when you know the zillion different things that can go wrong. But today we were reassured a little bit when everything looked OK, and we saw this (annotated for those unfamiliar with ultrasound):
2 little feet, 2 little hands, a beating heart, all kickin' around in there. It was the most amazing thing I've ever seen.
