36 weeks speeding labour up

What are the chances of bringing on labour at 36 weeks? 
I do NOT want to bring on labour I'm just scared if I have sex or eat pineapple or do anything else (really want to have sex) on that list I will bring Bub on and it scares the shit out of me I have already had 1 baby go to nicu (low blood sugar levels) and never want to go thru that again
