Baby before or after police academy

I really want to have a baby with my boyfriend. We've only been together for a year and we are both almost finished with school. Only thing is I plan on going into the police academy one day and don't know if I should have a baby before going into the academy or afterwards. I know that one day we will get married because a love like ours is magical. I just don't know what to do. I haven't really talked with him about it because he is really stressed with being back in school getting his degree and working at the same time. What should I do?
