Really want to have kids but too young- help?

Ok, I'm a teenage girl and I constantly think about having kids. Don't worry, I'm not stupid, I won't go out and get pregnant as a teen. But I think about the future too much, and can't wait to have kids of my own, instead of focusing on school and trying to enjoy my teenage years. I don't want to wish my years away, I want to make the most out of my youth. But how do I get rid of this baby fever, at least temporarily, so I can be a normal teenage girl? Oh and btw is this normal?
