"i have had my implant for about 10 months now, and i&#039;ve had a pretty good experiment with it. the changes i have seen are a slight raise in my moodiness, but nothing totally extraordinary. there was a big change in my period though, i went from getting it for a week every month to getting it for 3 weeks every 2 months. it&#039;s a pretty light period, but it&#039;s a little annoying having to wear pads for 3 weeks straight. i think it&#039;s worth it though, it does a great job of not getting me pregnant. when my 3 years is over i think i&#039;ll get it inserted again."
