"I had Implanon put in July 2009 because I have Ovarian Cysts and the pain was unbearable so we tried Implanon. It has worked great. I did have bleeding for almost three months straight after it went in, but I wasn&#039;t having pain so it was a great trade off. After the first 12 weeks were done everything has been great since. I have been having some pain recently that I think is my cysts, so I have to get it checked. I am wondering if the Implanon is wearing off. Since I have to have it changed in July because it has been 3 years I wonder if it is &#039;fading&#039; and therefore I am starting to have pain."
