Idk what to say! ?

So, I really want to try and conceive. But my boyfriend and I have only been dating a little over a month/: I know he's the one I want to spend the rest of my life with for sure! Although I have no idea how to bring this up, because idk how he will feel about having a baby so soon in our relationship. He's getting deployed and I'd like to start a family with him already. Please help me on how to bring this up to him!
