I have been off the depo injection since April 2014 (15 months) I have only had my period back for 5 cycles. The second and third and forth cycle I decided to use opks to track my ovulation, we had sex on all of the days we needed to. It was such a stressful time, and so disappointing when AF showed her ugly face at the end of each month. On my last cycle I had run out of opks so didn't bother to get anymore - didn't stress about sex, or ovulating. And to my shock have just received my BFP...so I believe it's true what they say, it happens when you don't try. We had fun and didn't stress..I wish everyone luck and send baby dust your way. Xx
