"i&#039;ve had the nexplanon in for 5 years. when it first got inserted it itched like crazy, but eventually it went away. i haven&#039;t had a period the whole time. no spotting or anything. i can&#039;t really comment on the mood swings as i&#039;ve been on anxiety/depession medicine for 15 years. now that i think about it, i&#039;m pretty sure it caused all of my weight gain, but i&#039;m not pregnant so there&#039;s that. overall i&#039;ve had a great experience."
