"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&#039;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&#039;t help.  my doctor said that with this medication used continuously there isn&#039;t enough estrogen and the body can&#039;t handle that sometimes.  i am currently using seasonique, which i haven&#039;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."
