It's possible. I heard depo isn't good for you though. I was on it and had a neighbour that worked at a doctors office and told me to come off it as soon as possible. I only was on it for maybe a year but that was in high school. I have 2 children but it was many years after being off depo.
Many women end up pregnant after the depo though.
Well I have been on depo since 2009 until 2011. And it had taken me long. But dey said it take long for depo to clear off yur body.
Yes you should be able to get pregnant. It may take some time to get regulated but I don't see why you wouldn't be able to. Good luck.
