"i am on my second insertion of implanon; i have never had any side effects. the removal of the first insertion left a scar so small that if i didn&#039;t know it was there i wouldn&#039;t see it - it&#039;s literally the size of a pin tip. the insertion itself is painless, as was the removal. the doctor will use lidocaine and iodine to numb the area. it&#039;s very simple and easy and only takes about 15 minutes for the entire process. on my first insertion i only bled for a week or so and nothing after that. on my second insertion i never bled at all. i highly recommend this birth control!"
