I'm a first time mom and very nervous also, I think it's normal to be nervous.
Honestly I was SO SCARED too. It does hurt, very bad. I had horrible contractions that took me from a 5 to a 9 in an hour and my epidural wore completely off so much that I felt my cathider come out, every single stitch afterwards and everything in between. But you know what? I did it. I didnt have a choice, I couldnt change the situation and it was reality. In the moment you don't think about it you just do it. Your body goes into a whole nother mode when you're in labor. But honestly, I know people that never felt one contraction and never felt any of the birth because the epidural worked so well. Either way, dont freak out. You can do it!
labor pain? don't stress out, that's what makes it worst. don't forget there's pain medication you don't have to suffer :)
