Hi i have been on depo-provera for about 4 years and got my period back, what are my chances of getting pregnant?

Possible: Probably not, but the best way to rule it our is to do a home pregnancy test once you are a week late, repeat in one week if negative.

Depends on your age.: Your fertility should return soon after stopping the depo-provera injections. Your likelihood of pregnancy depends on your age mostly (see attached graph), as well as on your past gynecological history (fibroids, salpingitis/pid). Take Folic Acid 1-5 mg daily, avoid smoking, maintain a healthy weight for your height - and good luck!
