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 there any advice I can get from you mom's out there that have felt/feel this way?
