"i&#039;ve had the implanon for just over a year now, and it&#039;s been very effective in preventing pregnancy. i originally went on it because i kept forgetting to take the pill and was always paranoid. i get spotting often and light but frequent periods, which is annoying. also, my skin isn&#039;t good these days and i believe that it&#039;s due to the implanon. i did not gain weight, actually lost 5kgs, however i&#039;ve been eating well and exercising. i can&#039;t imagine weight gain occurring if a person is active and eating well. no change in moods - i was already irritable prior. think i&#039;m going to have this taken out to balance my hormones."
