"back in 2012, i got the implant which was then called implanon. there aren&#039;t really any major differences between the two besides the way they insert them. i loved it! i had normal 5-7 day long periods and my mood or weight did not change. one bad experience i had was when i bled heavily for about a week. also, there is a scar from where it was inserted and removed. i&#039;ve recently got the implant replaced so now i have nexplanon. now with this one, i have been experiencing light spotting for 3 weeks on and off. i&#039;m not sure if my body still needs time to adjust to the implant or what. i&#039;ll just wait it out a few months before going to talk to my doctor about."
