birth control
"BE CAREFUL!!  After being on Ortho Evra for 2  years my insurance switched me to Xulane and I got pregnant within the second month of being on it.  My periods were consistent while I was on Ortho, but when I switched to Xulane they became very spotty/unpredictable, not to mention the bloating and cramping I felt.I was on my 3rd month before I realized I was pregnant.  Even though my insurance covered part of the Ortho, I still had to pay $50, with Xulane it was completely free.  But now we know why, you get what you pay for."
