Ethinyl estradiol / norelgestromin
"I have been on Ortho Evra for three months and my experiences so far have been okay. The very first week of starting the patch, I was very nauseous, had some diarrhea, and very bad headaches (however I think this would be the case with most methods). Usually the first week is the worst. 
Since then, I've had random headaches and nausea (mostly on the patch "change" days). Unfortunately, I had terrible abnormal vaginal bleeding that seemed to be like a heavy period for a little bit over two weeks. 
My only other complaint is that the patch gets stuck to my clothing a lot and it concerns me. Sometime it gets bubbles in it or it looks like its falling off. 
However, I like the ease of use, and the fact that it is not a pill."
