Nervous to be a mom

My hubs and I planned to get pregnant and we were so excited when we got a positive test but now that I have just over a month left I'm getting more nervous about being a mom. I'm still excited of course but I'm so nervous. I've never been good with anyone else's babies and I've always been told that it's different with your own child...is there any advice I can get from you mom's out there that have felt/feel this way?
