birth control
"I have had my implant for about 10 months now, and I'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's a pretty light period, but it's a little annoying having to wear pads for 3 weeks straight. I think it's worth it though, it does a great job of not getting me pregnant. When my 3 years is over I think I'll get it inserted again."
