Trying to get hubby on board

Hi there I'm 23 and so is my hubby. I work around babies a lot...I work in labor and delivery. I have several medical conditions and I would like to get started on trying. This is the perfect time to start since both of us are pretty secure in what we do and money wise. (He is in the military) I really don't know what to do or say to get him on board with ttc. I have had two chemical pregnancies in the past six months as well. We use condoms for protection and I don't see the point in using anything. All my docs agree that if I want children now is the time to start trying. I'm feeling a little defeated.
