Birth Control
"Nexplanon is definitely effective if you don&#039;t want to have a baby. I&#039;ve had it for 3 years and just got it replaced. While I was on it , my periods were irregular , light and longer but not painful. I had no issues with weight gain or weight loss. My moods were regular. I did notice when my nexplanon was expired , my mood swings were crazy and I uncontrollably ate and gained couple of pounds. Now that I&#039;m back on it, my cravings and moods have improved, but my period is way off. Like it&#039;s been almost 31 days and haven&#039;t seen any sign."
