Depo Shot

So I was on the depo shot for about a 1 1/2 on and off while I was on the shot I did not have my period. As soon as I would miss my shot or decide not to take it my period would come on time and regular. I have been off of the shot for over 3-4 years now with a period that comes every month.

Is there anyone on here that was on the depo shot and is having any issues with getting pregnant?
