Hard to know if you're trolling the site because you're bored or not. But here goes.
Sorry to be blunt, but you don't need to have children when you are not old enough to live on your own and raise them yourself.
Seriously - you want to have children when you haven't even graduated high school? I call BS on this question.
Finish high school, find a nice young man, marry this young man that has a job and an apartment and then settle down and have kids.
