"i have had nexplanon since may of 2013, it is now september of 2014 and i am pleased to say it has been a good experience. i haven&#039;t gained any weight on nexplanon. i actually feel like my sex drive has increased. i haven&#039;t had issues with acne. i&#039;ve had a period that hasn&#039;t lasted longer than a week and a half and have only one every few months. after reading other reviews i feel extremely lucky. the only thing i have to complain about would be that every now and then if i lay on my arm with the injection site i sometimes experience discomfort but that seems like a small issue and after my third year i plan on getting nexplanon again. hope this helps!"
