I am nervous about motherhood

The question I constantly got as a FTM is am I nervous to give birth? At first I joked about not being nervous due to the fact that he was going to com regardless. However, now I'm getting nervous! I'm 36w1d. That means I have less then four weeks left! Where did time go? At first I was staring at a pregnancy test in disbelief and now I'm getting closer to holding my little one. I'm nervous! I'm nervous that maybe I won't be as prepared as I thought I was. I'm nervous about afterbirth and will I be a good mother or how to take care of my little one to the best of my ability. I'm scared. I am nervous about messing up! I mean, this is another human being. This is someone whose gonna look at me for guidance. I feel so unprepared and terrified. Where did the time go? I know he is still coming regardless of what I say or do, but now I can say I'm nervous! It's scary, exciting and as much as I want him here( also to not be pregnant anymore) I want him to stay in as long as possible!
