"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&#039;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&#039;ve never had).  i had an unusually long 12 day period in early july, but haven&#039;t had another one since. occasionally i feel like i am cramping. for me, the benefits outweigh the drawbacks by far! i can&#039;t imagine what i did before getting it."
