Every birth and labour is different, if you want pain relief in the end then it's your choice.

My first was great apart for the fact i was induced, 14 days over!!!! and i had no pain relief only a 3 hour labour. My second was horrible, induced again (due to medical condition), massive amount of pain, I knew it wasn't me as i went pain relief free for the first, it was agonizing, i was screaming for the epidural!!! After 3hours i was still only 2cm's dilated, they gave me the epidural, the anestheisiest was still standing there i felt the baby crowning, as soon as he inserted the epi i dilated to 10cm and with in 20 mins bubs was born!! He was posterior!!!!! I was in so much pain that i was tensing up and could not dilate. It really depends on the situation!!
This time around i will be open minded , i will play the wait and see game!!
Whatever decision you make it will be the right one for you.
