Time off?

Has anyone here ever taken a break from trying, and lost their "mojo" or started second-guessing whether or not they even want to have children? I'm kinda freaking out. Hubby is soooooo ready, and I was, too. And then we started all of the testing, and I had to go on thyroid meds so doc said to take a break from trying until thyroid was regulated. Now it's regulated, and I feel like my baby mojo is gone. I love babies, but it's like the desire to have my own isn't a strong as it was. Am I alone in feeling like this?
