"i have only had implanon since december 6th.  at first, i was super excited because i would not have to worry about birth control, i could have a stress free sex life with my husband.  well i began my period that morning before the implant was in.  i figured, 5 days, and i would be okay.  my periods have never been just &quot;light days&quot;, but that is how this one was.  but, it lasted for about 2 1/2 weeks.  i spent a lot of time reading reviews and trying to determine if this was normal. after reading, i was convinced to wait it out and see if it would go away before contacting my physician. that was great advice. right now, i feel great. no other effects at all!"
