I want a baby

I want to be a mother so bad but I know I can't in this time in my life I'm too young, I'm just finishing up my massage therapy school and my boyfriend well is my boyfriend and not my husband we have been together for four years and we want to get married but again money is the issue. Once I'm a therapist I will be fine and he is getting his AA very soon. We will be moving around and we decided a good age to start trying is 25 but why now am I just craving to be a mom when i know logically it wouldn't be fair to my baby?
