birth control
"The Mirena worked for not getting pregnant and no periods. However, it gave me debilitating cystic acne. It started within 3-4 months after getting the Mirena inserted.  I went to several doctors and dermatologists who all insisted that the Mirena was not the cause. I spent thousands of dollars on acne prescriptions and countless depressed days due to the severity of the acne.  As a woman in my mid thirties,  it effected my career as well as my personal relationships and self esteem.  This went on for the next 5 years.  I didn't have the Mirena removed on its expiration date, and noticed that after about 3 months after the expiration, my skin had miraculous improvement.  I had the Mirena removed and have never suffered a breakout since."
