17 & TTC baby #1

I have been TTC for the past 8 months. My boyfriend and I had a pregnancy scare but then when we realized I wasn't actually pregnant, we were both devastated. It was then we realized we wanted a little one of our own. We had already been saving up money for the past 2 years we've been together. We have an apartment and are financially stable. We have well over $7,500 saved up between the two of us. We really are trying hard to get pregnant. Any tips from anyone who is or has been pregnant about getting pregnant? No negative comments please. Just need some support and advice from positive people. Also, I had fallen pregnant around July last year or at least when I found out I was pregnant it was in July 2017. We were so excited, I was 7 weeks pregnant. Then in September around 14 weeks, I lost my baby. This is another reason why we're TTC.
