"i have the nexplanon which because i once had the implanon and loved it and was told this was the newer version. this time around i have spotting that last for quite a few days it&#039;s not a steady flow as where with the implanon i had no period at all. but this doesn&#039;t stop my everyday routine or isn&#039;t to bothersome. i i had it in since november 2015 other than acne increase i have no complaints."
