"i got on nexplanon in mid july 2015. the longest i&#039;ve ever been off of my period since i got it implanted is about 2 weeks. since i&#039;ve had it implanted i&#039;ve gone between 2 to14 days per month with no bleeding, with the average being less than a week. i&#039;m 25, i&#039;ve never been on birth control before. i have gained about 10lbs, minor acne outbreaks around my upper back. i have experienced pretty regular tiredness and depression. a comment on here mentioned the dark, rust colored bleeding, i experience that regularly. i&#039;m super close to having it removed because of the constant bleeding. no arguing that it works tho. haven&#039;t used protection since i&#039;ve been on it. and the implantation process itself was not really painful."
