i only was on the depo for three months and i had horrible side effects. my period stayed on for 1 1/2 months. i got on the birth control pill and four days later my period came off. i m on a low dose micarette birth control.

I was on the depo shot for about 2 years. While on it i didn't get my period at all. The month i skipped getting the shot i got my period. I think it all just depends on the person. They say that with the shot it can take up to a year for your body to get back to a normal cycle. So there is a chance that you may not get it for a while and even when you do it could be a lil whacky. Like the 3rd month i was off the shot i had an extremely heavy period where i had to change my tampon like every hour. That only happened to me once. I think you'll be fine your body just has to get back on track, but if you are a lil worried it can't hurt to go see your doc.
