I'm 17 and I want a baby
Why would you want a baby? You are so young!
Because I want to experience the feeling of pregnancy and childbirth.
It's wonderful that you have such a strong maternal instinct.  You should wait until you're a bit older when you can financially support a child.  You have a lot left to experience and babies cost a lot of money.
Yeah, who cares about money when you can have babies? I'm going to stop worrying about money and find a man that loves me and agrees to have babies with me.
That logic right there is just proving that you are not ready for a baby. You should wait a little bit so that you are more stable in your life, and then have a baby.
