What can happen if I take yaz birth control pills as well as orthro evra at the same time?
I am not on them to prevent pregnancy because I have my tubes tied but, I am using them for the hormones

I STRONGLY suggest NOT combining them without speaking with your doctor first.

You should not have to combine BC. If you're having an issue with "hormones" as you say, your doctor can help you find the right BC to address your concerns.
