"i&#039;ve had my implant since march &#039;16. ever since i&#039;ve had it, i&#039;ve experienced severe headaches that happen at least once every week. i haven&#039;t had my period since i&#039;ve been on it which worries me because i don&#039;t know whether that&#039;s bad or good. i have gained weight. i use to always stay around 130-140 for about 4 years and now i&#039;m at 170. other than that, i have no cramps so this thing is an ok for me."
