I want to be pregnant (16)

I'm 16 and I really want a baby... I'm ready to save my money and have a job. I don't have a boyfriend and that doesn't change the fact that I want a child. My friends keep reminding me how young I am and that it's too soon but they know I've been talking about that for probably more than a year ago. I probably feel alone and that does not help. People will say "you have so much to live" but honestly I have so much to live with my child. Can someone tell me something that will change my mind about having a kid at a young age?
