"i have had implanon since june 10th 2012. i haven&#039;t had my period once, not sure if that&#039;s a good thing. i haven&#039;t spotted, but i&#039;m not complaining. i have not got any acne. i have however gained almost 100 pounds. and i haven&#039;t really been able to lose weight while on the implant. and just recently my sex drive has almost nearly disappeared."
