17 and TTC

Okay, I know what most people probably think. I'm crazy. And maybe so, but I know what I am ready for and can and cannot handle. My boyfriend is in the Army. He is without a doubt my one and only and I have no questions about it. He brought up trying to have a baby when he's home for Christmas. I thought about it and it grew on me. He has income with the army, he'll be based soon, I'm graduating high school in 3 weeks, I have a steady job in which I just got promoted, vehicles and housing won't be a problem for us, and I know he is who I want this with. I'm about to be 18 and he turns 19 soon. We really want this. And we know it will NOT be easy, but we agree we can do it. Anyone in a similar situation?
