"since i only ever see negative reviews of nexplanon, i thought i&#039;d share my experience with it. i&#039;m 18 years old, and got nexplanon inserted in april this year. at first my periods were a little unpredictable, with prolonged bleeding and irregular spotting, but everything evened out eventually. my periods actually stopped completely about two months ago, which i enjoy. i haven&#039;t experienced any side effects; i actually lost weight (although i&#039;m not sure if it was actually caused by nexplanon). it has worked out wonderfully for me!"
