birth control
"I have had Implanon since June of 2010.  So far I love this method - I get so excited when talking about it. I think most of my friends are tired of feeling my arm. I haven't noticed any severe change in mood or weight, however there was an increase in acne on my face and on my back (which I've never had).  I had an unusually long 12 day period in early July, but haven't had another one since. Occasionally I feel like I am cramping. For me, the benefits outweigh the drawbacks by far! I can't imagine what I did before getting it."
