Induce

My OB won’t induce me until I hit 41 weeks. Is there any way to be induced right at 40 weeks? I’m in so much pain and can hardly move even to just turn in bed. I’m 38 weeks and I honestly can’t handle another 3 weeks. Would the hospital just induce me without my OB knowing if I went at 40 weeks or what can I do? Thank you for any advice!
