Birth Control
"I was on Yaz for a year and a half, and then decided to switch to LoSeasonique so that I would only have 4 periods a year.  Big mistake!!  I am switching back to Yaz because of the side effects of LoSeasonique.  On Yaz, I always knew when my period would start, and it was only about 3 days.  It also helped with my awful cramps.  I had no bad side effects from Yaz at all.  I would definently reccomend it, but know that every pill has a different effect on each person."
