"i initial got the nexplanon february 2015, so i&#039;ve had it for a year and some months. i bled lightly for the first month than nothing after that. i just noticed spotting for the first time after a year and 6 months. hopefully it won&#039;t last long because i don&#039;t like periods and don&#039;t want to have any. other than that i have not experienced any side effects up until now. i never break out with acne but have just started. i&#039;m already an emotional person since before the implant so i don&#039;t want to say it&#039;s caused mood swings. it&#039;s worked wonders for me thus far. the spotting after a year startled me but i assume it&#039;s normal after doing some research. i don&#039;t have any complaints and plan on using this method again after my 3 years are up."
