39 weeks, scared for delivery?

So, I got pregnant after my 2nd child was 4 months (a lovely surprise fail of birth control). I'm due in a week, just curious if it's normal to be absolutely TERRIFIED for delivery? I don't remember being this scared with my second son, but there was a 2 year gap between them so I'm thinking it could just be that I had more time to get over the pain and all that of delivery. My 2nd son was a very strenuous, unmedicated (not by choice) childbirth and it was very traumatizing...now I'm dreading the second I go into labour...is this normal? and...is there any ways to feel less scared at all about it? I do want the baby out so I can have my body back...but just trembling at the thought of it all.
