"i&#039;ve had nexplanon since february of 2015. i got it for birth control but more importantly to try to regulate my periods because they were so painful and heavy for me in the past. the side effects i&#039;ve experienced is the irregular periods. it made my periods lighter and less painful but they lasted longer. i bled off and on for nearly two months so i went to the doctor and they put me on the pill to attempt to regulate my period. it worked for a little bit but now they&#039;re back to being irregular but they aren&#039;t as long as they were. i also experienced a pain at the insertion site and still do occasionally. emotional side effects i&#039;ve experienced would be mood swings and sometimes sadness. all of my symptoms are tolerable. i&#039;m glad i got it."
