Inducing opinions.

I'm a little over 36 weeks and dilated at a two. My doctor told me I'd have back labor, because of problems before pregnancy. I've had a lot of back pains lately, and my belly gets hard when it hurts most. I've been writing down when my belly gets hard and hurts and it seems to be every 5-15 minutes the last 4 hours. If it's not labor, what are the chances inducing will work without needing to do a c section because inducing failed?
