Confused about my feelings

I am 19 and getting ready to find a job and move out on my own after 2 years of college. I know I should get established and what not before I try to have a baby but I have the WORST baby fever. I want a baby so so so bad and my boyfriend has times where he wants to try and others when he's totally against it. I just don't know what to do because a baby is something I really want. I know I should wait but I can't help how I feel about it.. Help ?
