Unfortunately, in life and giving life there is a pain involved with the contractions and the baby moving down the birth canal and out into the world. No matter what mother on earth, be it an animal or human that give birth to a child there will be some sort of discomfort involved in the delivery process.
The best way to make it through the delivery is to prepare yourself ahead of time. I would suggest going to birthing classes where they can teach you some fantastic techniques in breathing and other ways to help you make it through labor.
Some people breeze through labor and have a simple delivery. This is because they are not worried about the pain associated with giving birth. They have mentally prepared themselves for the big day and when it arrives they endure the pain like it was a small stomachache and delivery their child. While other people have a very low tolerance for pain and have a very painful delivery of their baby.
I will tell you this and I have heard it from more than one person that has given birth to a child that the pain is forgotten once the baby is born. You can't actually remember going through all that pain after the child is born. If you try to ask a person what it felt like all they can say is yes it hurt, but I can't really remember much of it. I think the pain seems to vanish when you are finally moved to the delivery room and the happiness takes over as you wait to hold your baby in your arms.
You'll be fine, just take the birthing classes and prepare your mind mentally and you'll make it through this. Everyone has been there and in the end you'll love the experience and more than likely have a second child.
