It's different for each individual .Woman. Your doctor can prescribe medication that will cause you to have your period (my friend uses them regularly). If you are concerned, you should make an appointment to see your doctor. It could take up to a full year for you to start ovulating again but in theory you should be experiencing a regular period again.

Thanks for responding I dont have insurance but I think I might go to a free clinic or something

You can go to planned parenthood. They may be able to give you an idea what to expect.

You're lucky! I finished my depo in january. Bled the whole time I was on it, and have bled since I stopped taking it until just today!! Today is my first blood free day in like, 9 months! Lol

When I stopped taking my pills (ortho novum) in may 05, I didn't have another period until september 05. Then I went and got on a different pill (ortho lo) and my periods have been regular since then, and I am not emotional like I was on ortho novum. But, it took almost 4 months to get my period back after stopping the pills.
