Demo is a progestin, and thins the lining of the womb.  Many women either have light irregular bleeding or no menses while using demo.  It can take six months to a year for a normal cycle to resume, but it is out of your system completely by a year.  Your irregular/absent menses has another cause such as chronic absent ovulation due to a like of cycling in your hormones.  It is important to have the reason looked in to.  In some cases uterine cancer can arise from this condition. Please see a competent gynecologist or reproductive endocrinologist.
