"i had my implanon inserted a little over a month ago and haven&#039;t experienced any negative side effects. in fact i&#039;ve had just the opposite! i have been on the depo shot for the last three years and was a complete wreck as far as emotions and mood swings go. since my implanon insertion my mood swings have calmed a lot, they haven&#039;t completely subsided but they are much less frequent. no bleeding at all still but i haven&#039;t had any since i started depo so i&#039;m not sure if that&#039;s related at all. the insertion was quick and painless the only part that hurt was the shot to numb it. there was a nasty bruise but it only lasted about 3-4 days. other than the bruise itself my arm wasn&#039;t sore at all."
