Is there any women that were on the depo shot for a Long time and then got off of it and had a difficult time trying to get pregnant?

I was on the depo shot from the time I was 16 until I was 24. I've been off the shot for about a year n

ow and we've been trying since I've been off of it and I can't seem to get pregnant. Is there anyone else that had a hard time?

(little birth control history. I was on the depo for the time but I also had the mirena also. But I had difficulties with that. And returned to the depo for a year)
