Did you get pregnant by the pull out/withdrawal method?

I would like you to state if he ejaculated before you had sex or not. I've been searching up on this a lot because I've seen many questions asked on this and want to see! So I've looked on various sites and a lot of them say pre-cum DOES NOT contain any sperm,very few men have sperm in their pre-cum(this was a study between a few men) it is said that the only way you'll most likely get pregnant is if the male has ejaculated before he had sex because there could still be some sperm left over. So for all of you who have gotten pregnant by this method did the make ejaculate before intercourse?
