Birth control rash!

So I'm on the hormonal patch. And I've been on it since I started my Accutane treatment. But I started getting SO itchy under the patch and it became unbearable I just took off the patch since I was no longer sexually active. And it even left the little square mark on my skin which is annoying. But I decided to put it back on Sunday morning, and felt a light tingle, and next thing you know it itches like crazy again. I don't know if it's because my skin is sensitive right now, or if I should just switch to another form of birth control.
