Apathetic?

I'm 37 and a half weeks, and I don't feel excited for my baby to be born. I feel kinda apathetic and neutral about it, which makes me feel like I'm already a bad mom. We have the nursery set up and everything we need, but I don't even feel like going into the nursery anymore. I used to just go in there and sit. I think I'm nervous for the actual birth, but idk. Any other first time mom's feeling this way?
