"i had implanon implanted two years ago. the first month i had my period for over 18 days. i experienced such changes with my hormone levels that i would cry, or be outraged one minute from the next and i couldn&#039;t control the way i felt. i&#039;m a completely rational person and whatever hormones are in this literally made me want to cut it from my arm. 
after the first three months, of which i had four days each of the rage/crying/uncontrollable emotions, everything seemed to level out. i haven&#039;t had my period for a year and a half now. if you make it through the first three months, it&#039;s great. "
