"i have had nexplanon for 5 months and i have mixed feelings about it. when it first got inserted i have a period for about 2 weeks and then didn&#039;t have one for about 3 months (woohoo!) but now i have had spotting for about 3 weeks and it is just annoying. i haven&#039;t experienced any other side effects which is why i give it an 8. i just want the spotting to stop! a friend told me she had experienced the same thing but her spotting only lasted two weeks - hoping it stops soon."
