Refusing an IV during labor

I was admitted into the hospital a week before I found out I was pregnant for 5 days and I absolutely hated having an IV. Usually needles and being punctured doesn't bother me but they had put my IV on the inside of my right arm where my elbow bends and it hurt like hell for 5 days. I couldn't even move my arm once I got out because it was so sore and weak. Now I'm panicking because when I go into labor I know they have to put me on an IV and I feel scarred from last time. I really don't want it. I understand having it during labor incase of an emergency but I want them to take it out afterwards. I will drink any amount of water and take any pills just so I won't have to have the IV in for long. Would it be dumb for me to refuse it in the first place?
