Ways to induce labor?

As
I'm almost 39 weeks & I seriously can't take this anymore. Been dilated since 35 weeks and I need to get this baby out. My dr won't induce until 41 weeks and I seriously can't deal another 2 weeks. What are some ways that might actually work to naturally induce? 
I walk everyday for about 2 hours
& I've tried nipple stimulation but nothing so far
