Excitement Slump

Patrick
My wife and I were talking last night and I told her that I haven't been excited about having a baby as I was a few weeks ago. I think it's because we're in this "no mans land" time where we've had the initial excitement, the anxiety of waiting to tell friends and family, told friends and family but now we're at 16 weeks and it's too early to start doing anything with a nursery, we haven't felt the baby move yet and at our last appointment we only got to hear the HR and not see anything. 
Has anyone else gone through this slump?
