"I was on Ortho Evra for 4 years and absolutely loved it!  I had no problems with it up until the last year.  I recommend this product 100%, if used like package states.  It's very easy to use and very convenient, I mean how easy is it to remember to switch it once a week?  Very effective as well!  I used it continuously (with no off week) because I had really bad headaches during my period week and loved it at first, until about 6 months later and I started have a lot of horrible cramping and breakthrough bleeding.  The cramps were more frequent than the bleeding, but just as annoying.  I talked with my doctor who told me I needed to force my body to have a period, so I tried that (took the patch off for a week) and that didn't help.  My doctor said that with this medication used continuously there isn't enough estrogen and the body can't handle that sometimes.  I am currently using Seasonique, which I haven't had any problems with yet.  I wanted to let everyone know of my experience, but that I still recommend the product, just not for continuous use."
