Pineapple to bring on labour?

Im 39+4 and just want my baby here now, my first was 2 days early so I'm dreading goin over this time 😫😫 Im going to buy pineapple today, how much are you supposed to eat? (I know it's obviously not proven maybe even just coincidence that it brings on labour but I just wanna try!) any other theories I can put to the test?!Â
