"i chose implanon because it lasts for 3 years, and i am terrible at remembering to take pills. i had it inserted july 2011, it has been 4 months. the procedure itself was easy, i was impressed with how little discomfort i felt. the area was slightly tender for a few days, but honestly once it was inserted. i can feel it in my arm, but you can&#039;t see it at all. i have not had a period since, and have had minor cramping, but this is normal for my body, was the same when i was on the pill. i have gained weight, 10 pounds. this could be a mix of things (traveling a lot), not just implanon, and i am now working out like a mad woman and eating clean. hopefully it comes off! i give implanon 9 out of 10."
