I have been using the evra patch for over 2 years now, Over the last few months my periods have been irregular I'm also experiencing bad mood swings I get really angry with everything and everyone I take panic attacks sometimes every day it's causing a lot of problems such as loss of appetite sore heads and Im struggling to talk to people in case I explode, I'm unsure if this is the cause of my mood swings and looking to see if anyone else has experienced this?
