Kind of need some history here....
So, you have a baby..so you've had periods before? Have you ever had other times in your life without a period? Or just now? And how long has it been since you had a period? And when did you start having periods after delivery?
I think your profile says you have an 11 mos old? So, you did start menstruating regularly again, and then stopped?
Honestly, being married to a military guy, working FT with a baby...sounds reason enough to stop your periods. That's a lot of stress on ones body. Unless you are unusually happy in every aspect of your life, love your husband, baby, job, in-laws, housing environment and are a healthy, natural weight...periods can cease without warning when under duress or one is too thin.
