birth control
"Been on it for 4 months. I think I'm allergic to the adhesive.. It made the area I had it on really itchy. Not just right at the patch, it will travel about 5-8 inches around it. I hated the gummy, lint catcher look around the patch. Mine would get very loose around the 5th day. Probably due to scratching. My boobs itched like crazy! Very tender. Lots of muscle cramping wherever the site was at. Example : if I had it on my left butt check I would have Charlie horses really bad on my left leg.  And my headaches were super bad on the no patch week."
