Wanting a baby..

I am 22 and my boyfriend is 24 we both really want a baby but feel we are not ready. Niether one of us has anything against having a kid before we get married. He is almost done with school and I have another year and a half. Niether one of us  have a steady job. Also we live in different state at this time but will be living together come this May. One of his best friends just made her pregnancy announcement on facebook. Many of our friends either are preparing to have kids or have them. Having a child is something I have wanted my whole life. I am having trouble handling the fact that everyone around me is having kids and that's all I want.
