Questions about Induction (FTM)

I'm 40w5d & having NO signs of any progress what so ever. I've been 100% effaced & a "1" for over 3 weeks now, with no further progress. No contractions, no BH, I may or may not have lost my mucous plug (looked like the consistency but was snot colored, no red or pink). We have tried all the sayings to induce labor... I've walked every single day. Ate pineapple until my mouth was numb, had sex until I just couldn't handle the discomfort anymore etc. Nothing is happening. 

I'm hurting so bad though. I can't even bend my legs to put on my panties without being on the verge of tears. It hurts to sit, stand or lay down. My back feels like it's going to snap in half. 

My doctor hasn't even mentioned inducing but I go back to the doctor Wednesday. How can I talk my doctor into inducing me instead of making me go 42 weeks?
