When to plan for a pregnancy

Loretta
I'm a military wife and we got married this January. Recently I've been trying to calculating when we should start trying for a baby. My husband goes on deployment for 6 months in a august 2018 and we leave not much later for another base, which leaves me with just me and him and none of my family, and we both agreed we would have a family before leaving because my family is here and I don't want to be alone during my first pregnancy without any advice or anything. So I've calculated it multiple times and it looks like the best time to start trying is this August, September and October. Before my husband ships out and before we leave. I think it's perfect but I'm not sure. Any advice?
