1 year of trying no baby and now a deployment

Feeling really frustrated! We been actively trying for a year ovulated right before Christmas only for my period to start today. It sucks because my DH shipped out for a deployment two days ago with a up in the air return date. We have 2 children I love them dearly i just dislike the age gap that will happen if we are to be blessed with another child in the future. Everything happens according to the higher power will. I am just really discouraged right now.
