I was on the depo shot off June 2014. I have been trying to conceit every since, but I was never tracking on when I ovulate. I started to keep track last month AUG 2015 after talking to my doctor an she was saying just track your days an BD the day before the day of an the day after. AF didn't come on the 8th so couple days later 9/12/15 I took a HPT an got a BFP. The depo I don't recommend that birth control it takes so long for your horonmones to get normal, but everyone is different. Good luck to all of you that's TTC ❤️✨✨✨🍼
