I had implanon for 3 years, I got it taken out in October of 2012, it is now September 2013 and I still haven't had a period. My husband and I wanted to try for another child, and my doctor okayed it 3 months ago, but we still haven't conceived. I have taken numerous pregnancy tests, all negative. I have also taken ovulation tests, which say that I am ovulating, but I still haven't had a period. What is going on? Should I be concerned or is this something that happens after getting the implanon removed?
