"i have been using implanon (nexplanon&#039;s original brand name) since 2003 when i turned 37 (am now 50), renewing it every three years until it became nexplanon. i can report a 100% positive experience all these years, and i intend to continue until i finally menopause. my weight has never fluctuated; periods very seldom - maybe four times a year and very light; maintained my clear skin."
