I was in your situation. I switched, and never looked back.
The patch uses similar hormones to the pill. They're released via a trans-dermal patch, which you have on your skin for seven days. You alternate sites and sides of the body. Three patches on, one week off, and you cycle starts again.
Because of the similarities between the pill and the patch, the side affects are very similar.
Only one company makes the patch right now--Ortho Evra.
But, like with all decisions like this, your doctor is going to have a better idea of what will work with your body. So, ask your doctor and see what they recommend.
