My depo shot wore off in July 2014. I went on the pill immediately after and stopped taking the pill to start ttc October 5th 2014. January 29, 2015 I got my bfp! Don't give up ladies! I know the stories about no success even after years of trying can be really discouraging but it can happen! I strongly  recommend the use of opks and don't stop testing until you recieve the positive ovulation test I'm 100% sure that's what did the trick for us!
