Natural start of labor?

I was induced with my son last year 10 days past my due date with pitocin. I'm having another little boy in a few weeks and I'm really nervous about having to be induced again. All the research I've found says that contractions and pain and so much more intense when you're induced, I opted for the epidural last time due to the intense pain and i wasn't dialating, but I'm really wanting to go all natural this time around. Just wondering what my chances are of labor starting on it's own this time?
