Is this normal?

Hubby and I have been ttc for a year. I have wanted to get pregnant SO bad since we started trying. We have had zero pregnancies and are starting to loose hope. At times I want it so badly that I catch myself day dreaming about it. Day dreaming about finally seeing a positive test, how i would react, cry? Probably. How I would tell the hubby. How he would react. I picture myself with a growing belly. I even picture seeing my babies face for the first time. Have any of you that are having trouble conceiving ever done this? I am sure that many of you want a baby as badly as I do. Baby dust to all of you!!
