"i&#039;ve had implanon for a little over a year. it&#039;s been pure hell. i have gained 60 pounds, and nothing i do helps me lose weight. my depression is extremely bad from the hormones. (i had depression before, but it&#039;s 10x worse). for the first four months i was bleeding, with a 2-3 day of not bleeding. my periods are now, about 9 days long. i have irregular periods, so it goes from period with 3 weeks off, to period with one week off. it&#039;s just all over the place, with extremely painful cramps. i&#039;m getting it removed tomorrow, thank god. i&#039;m terrified of hormonal birth control now, this being my first one that releases hormones. while i have had a horrible experience, i hope that others do not. it might work for you, it might not."
