"i rated this a 4 because it has been in my arm since december 17th, 2012, and just a few months it finally comes out. i have had nothing but trouble with this thing. my first period on it was 3 months long. 3 months long! i was told that my periods would be lighter, and less time, as a week was my normal. oh no. not anymore. when it comes its at least 2 weeks. these past 2 months have been horrendous. i was on 3 weeks, with super bad cramps, off one week and its been 2 weeks on again and the cramps are horrifying. i was told several times to let my body adjust, its normal... its been 2 and a half years, and i&#039;m not dubbing this &#039;normal&#039;. this thing cannot come out soon enough. it worked on the not getting pregnant part."
