Hi, I just got a sample of the patch from my doctor and a whole booklet along with it... But it says that it can be worn on your buttock, lower abdomen, upper torso( on your back though, not on your chest), or the outside of your upper arm... It also says you can put it in a different spot each week so that your skin wont get irritated, but idk if it reduces effectiveness if you have been putting it on your thigh.. But I wouldnt take my chances if I were you!

.. And if you have any info on the new warnings about the patch reply back.. I am scared to start using it now that all these things on the news about blood clots and the patch came out...

Hope this helps! :d
