birth control
"I've been on this for a little over a year (it just came on the market in the summer of 2007), and I have had no problems with it whatsoever.  No breakthrough bleeding, no spotting, no periods (unless I missed more than a pill, then I had some light spotting).  I've had so many problems with other birth controls, ranging from Depo, to the patch, to the ring, to 13 different types of pills, and I finally found one that worked for me!"
