Terrified about labor

This is my second baby. I’m 22 weeks pregnant and I’m starting to freak out about labor. I didn’t have complications with my first but the pain of the contractions were out of this world. After I had my first, I told people I would never have another baby again because of how badly it hurt. I always described it as someone sawing your stomach. Once I had the epidural I was fine but getting to the point where they will give it to me, has me staying up all night with anxiety.
