The Army recently recalled her, four years after it released her from active duty.
Pagan says she has no one to take care of her kids.
So she reported for duty Monday at Fort Benning, Georgia with both children, 4-year-old Elizabeth and 3-year-old Eric.
That's when she found out she'll be discharged.
Pagan's attorney says it's not clear if she will get an honorable or general discharge.
