The depo stays in your system for 3 months that's why u have to get it every 3 months. Usually takes 6 months to get fertility back but like I said I got a 5month,old off of depo and when I went to the clinic the doc said its very common now a days to get pregnant on shot. I had 2 shots when I got pregnant.
@sabi.bishh, again it varies. I have not heard good things about the depo. A girlfriend of mine only got two shots and it messed with her for about a year.
