i couldn't read and not reply, i know there are other women here who have some AMAZING and ENCOURAGING stories they can share.

My suggestion would be to research, research, research and where possible talk out your fears.
Talk to your MW's and the hospital about your concerns and ask them all the WHAT IF's, i think it's only natural to fear the unknown and even more so after a horrible experience.

I was lucky in that both my girls were drug free natural labors, but for myself DD1's birth was a little traumatic and it did take a bit to get used to the idea of laboring again with DD2.

I hope you can settle your nerves but in the end you do whats best for you and your baby, if thats natural then give it all you've got, if not then thats fine too, make a decision based on whats right for YOU.
