I feel very bad about this.

I was pretty excited about my pregnancy. But lately I don't even feel a connection with the baby. Not that I don't care but I just don't feel pregnant at times and when I realize I am, I just can't feel that excitement. When I do start to think about the baby, I want to cry. Most of the time, I'm worried I won't feel a connection with the baby once it's born. I need help, i want this to go away.
