41 weeks and trying not to get induce

I'm 41 week today(Wednesday) and I was suppose to get induce today but postponed it for Friday just because I want to give my little girl a few more days to come on her own.. I've been trying some stuff to help me induce naturally.. I've been taking and inserting evening primrose and taking and drinking raspberry leaf tea. I even tried Castro oil last night (2 tablespoons) and nothing.. does anyone have any other suggestions that may help.. I haven't tried spicy food 1 cause I know I won't be able to eat it i can't eat spicy and 2 I have bad heartburn.. oh yeah and I've been bouncing on the exercise ball too. any tips that can help me out are welcome.. thanks ladies
