birth control
"I am on my second implant.  I got my first one in 2001 in Australia, where it was only $23 (Aussie money, so under $20US, AND THAT'S WITHOUT INSURANCE).  I moved back to the US and had a difficult time finding a doctor who could remove it.  In 2008 I was living in OR and found that they had recently brought Implanon back to the US and I RAN out to find a dr.  The first time I had it in I had a 24/7 period, heavy, no joke.  But after that it stopped completely.  After my first one I went through Depo Provera and then The Patch, but nothing is as awesome as Implanon.  A word of advice: menstruation for me on Implanon is DIRECTLY related to weight gain.  If I go over 150lbs (at 5'10") then my period starts. Under than I'm clear."
