"i got the nexplanon on april 10, 2013. so i&#039;ve been on it for 8 months. i was warned about the side effects and that some woman&#039;s periods go away. the day after it was implanted, my period stopped and my arm ached for a few days. for two or three months i had very light periods that started on the 10th of each month. no joke. then my periods disappeared for a few months. which was awesome!!! the past few months i have had my normal period. other than randomly not having periods or having my periods and my arm sometimes aches, i have had no scary side effects. i definitely recommend it."
