birth control
"I had been on the patch for about 3 months. I had noticed a bit of mood swings, and my breasts grew as well (bonus). Unfortunately for any of you women who have sensitive skin or are allergic to certain chemicals, I was allergic to the sticky glue on the back of the patch. Whenever it was on, I would be extremely itchy and have a terrible rash. It became so bad that I still have scars in the shape of the patch all over my body...So if you have sensitive skin then be wary  that the patch may cause a reaction!!"
