How long?

Carson

I havent been on the depo for over 2 years, almost 3. I was using this birth control for 2 years before getting off it. Ive been taking OPKs and was supposed to ovulate days ago as my fertile window was supposed to start last Thursday. I don't think I'm ovulating. how long had it taken everyone else to get pregnant or have the hormones completely gone? I feel like I'm failing my fiance.
