Up to 6 month: It may take up to six month after you stop the pill or the Depo-Provera shot.

Needs evaluation: I am assuming you are no longer breast feeding. If it has been 2 years since you had a child and you haven't had a period yet, if it has not been done yet, you need to be evaluated for the cause, especially since you didn't even get periods on the pill.
