I've been on depo for the last year and was supposed to be getting my shot again this month after my period. It never came at first I didn't think anything of it until my breast became sore and I started feeling nausea during the day. Took 2 test both pregnant! Then saw my Dr pregnant 6 wks along. OMG!
I was on depo for 6 years, got off it and did birth control pills for a year, and if took a year after stopping the pill to get pregnant.
It took my husband and I 3 years after the depo, I was told it stays in your system for that long after you're last shot. Good luck
I went through the same thing after being on the depo. It took forever for my period to come.back normal. My husband and I tried for almost 2 years before getting a positive hpt. Hang in there, your body just needs to get your hormones back on track.
