"i had my nexplanon implanted august 2015. the insertion was a breeze. the most painful part was the shot. i experienced no discomfort at all during or after insertion. my period before was heavy with light to medium cramping. after insertion, my period became very light. i went from having to always wear overnight pads to regular. after about six months, my period became very erratic. it was impossible to know when i would start or for how long. my hormones were very out of wack from the first day of insertion. i was very emotional the entire time i had my nexplanon. i also gained nearly 30 lbs. i finally had it removed after having a period for over a month."
