"i have had my implant in for nearly two years. every month that i&#039;ve been on this i&#039;ve had a period every two weeks, am highly emotionally unstable, and now if this thing couldn&#039;t do it&#039;s job any worse, i&#039;m pregnant. so no, i&#039;m giving it a 2 since 2 years was about how long it lasted. not worth it."
