"so i&#039;ve had the implanon for over a year, and it&#039;s been great! i&#039;ve always been a healthy person. i&#039;ve tired birth control pills and the ring (nuva right?) in the past, and i haven&#039;t experienced any side effects. i dont have health or mental issues. the implanon didn&#039;t change my mood or weight. i&#039;m still at 122 lbs. i don&#039;t exercise level is low (college student). i&#039;ve been reading all these crazy reviews about people gaining weight and losing hair, but thankfully, it hasn&#039;t happened to me. i do have to say, i haven&#039;t had my period since it was inserted into my arm. not even spotting. i don&#039;t know if that&#039;s bad. other than that, i&#039;ve been loving this birth control."
