"i got implanon in 2010 when i was 19, the first three years were fine. when i got it replaced 09/2013, the problems started. i didn&#039;t bleed the first month, but october until this moment i haven&#039;t stopped! the headaches are bad too, lasting days at a time (i&#039;ve learned to ignore them) but i know this is because my blood pressure is never under 160. other than that everything is fine. i didn&#039;t gain weight, but lost some when i got off the pill. most important, i&#039;m not pregnant yet! i love it, but its to each its own."
