breast milk early

this is a really weird question and may be common sense but im not sure.. I've heard alot of women say their breast milk didn't come in till 3 days or more after deliver. is it possible to try to get it to come in earlier by trying to pump or using nipple stimulation or something? sorry if this is a stupid question I'm a ftm and just curious. i plan to exclusively breast feed and didn't want to feel like i was starving my baby.
