birth control
"I started Implanon December of 2009.  Everything was wonderful for the first year and a half.  I didn't have my period or PMS symptoms whatsoever.  Less than a year ago I started having PMS symptoms and within 3 months I started having my period again without any reason or cause.  What is my worry is that I am ovulating and I am not sure if it is working anymore.  My periods have been worse than when I was on the pill.  I also didn't like the cost of the Implanon. Due to the cost and the fact that I am not even sure if it is working anymore, I can't say I have been happy with Implanon."
