Need some input on a sensitive subject

Hey everyone, I am new to this app actually and I want to start off by saying how much I love it. There’s nothing better than seeing such positivity and good vibes everywhere you look throughout this app and it makes my heart so happy. So, on to why I wanted to make this post... I am 19 years old and am newlywed to my high-school sweetheart of 5 years. He is in the military and we are stationed on Joint Base Lewis-McChord in Washington state but we are both from a small town in Georgia where the rest of our family and most of our friends are. My husband and I have had quite a few sit-downs and talked about what we would do in situations such as if he were to get deployed, if I were to get pregnant, if something were to happen back home, etc and we both have been hinting at each other that maybe we would like to start trying for a baby... I know what most people think about marrying young and purposefully getting pregnant young. Most negative feedback goes in one ear and out the other for both of us, but I truly want to hear more from other people on this. We both have baby fever to no end but what would be your mindset. TTC? What if he gets deployed? We both want kids before 21 (we aren’t the drinking type anyways) and along with moving cross-country with nothing but a suitcase and a $100 bill, we have overcome everything thrown our way and are living comfortably with no weights on our shoulders. We feel like a child would be tough but I haven’t met a single mother who says their children weren’t worth the struggle. And with him being enlisted, the military has great benefits when it comes to soldiers and their families as well. (By the way, I’m sorry I’m all over the place I’m just typing as I think and I get super anxious talking about things such as this)
