Implanon
"I have had mine in for almost two years now and the bleeding is almost a constant.  I am on my period more often then I am not, which of course equals very little sex.  I kept hoping it would change and I would not get a period like my doctor said would probably happen.  Over the last year I have had problems with extreme fatigue, backaches, joint pain, difficulty sleeping, and horrible acne.  I get it taken out in two weeks and can't wait.  Unfortunately I should have done it sooner but I did not think about Implanon as a source of the problems until my husband mentioned that it's probably my birth control and after checking the side effects sure enough all of my ailments are side effects.  We'll see if I feel better after removal."
