I had the implanon inserted Feb 09 its been 7 months now the first 4.5 months were great but since then I have 3 week periods very very heavy the cramping isn't so great either. I'm now on my 2nd week of another period. Am very tired and no interest in sex either as alot of you are experiencing. I have 2 children and always had problems with periods have tried 3 different pills this year and all have failed due to some reason or another. I did alot of research before I decided to get the implant in and I went to a Doctor to discuss my options also. He said give it a try and see how you go. Well I have and am just about to get it taken out. Am exhausted...
