"i&#039;ve had my implanon for about a year now and i love it. i&#039;ve had one period that lasted about a week, with very light bleeding. i do however get everything that comes with a period, the cramps, mood swings, all the emotions, everything but the bleeding at least once a month, as if i were on my period. other than that i have gained weight but like most people that&#039;s not just because of the birth control."
