I want a child but husband doesnt want to start trying yet

Alicia • Wife Mother of twins
So since I was 16 I've wanted a child but never wanted to be a teen mom (not bashing just knew it wasn't the right time for me) I've been with my now husband for 4 years im 18 now. I hate being on birth control I'm miserable all the time. He doesn't want to start trying until he can be home for the pregnancy the birth and after. But we are military so the likely hood of that happening is veryyyyyyyyy slim. He said in a few months (to start trying). But it isn't like I can't wait to start trying in a few months it's more of him pushing it off just to get me to stop talking about it. We are financially stable and have our own place. I don't know what to do or how to stop the overly baby crazy stuff. You know the saying "I don't think we are on the same page" yeah rn I don't even think we are reading the same book. Idk how to communicate it to him with out feeling like I'm pushing into something he doesn't want yet. Cause I think the first year we were together we both made it very clear we wanted children.
