Military Wife

My husband is gone away for basic training an I'm ovulating. An we didn't get to do it before he left we have a son. I had 2 miscarriages an we are trying for a girl. Am I wrong for when I go to his graduation to want to snatch him away an leave our son with his grandma ( whom he hasn't seen since he was born an he will be 1 next month) an start working on our daughter or son. I checked my calendar an I'll be ovulating again when I got see him it's been almost 2 months. Please help
