abnormal uterine bleeding
"I have 3 children and just had my third Mirena put in today. The cramping has already stopped. I love the Mirena because the last 2 times my period disappeared. Also, My libido is usually good and I don't have to worry about taking the pill. The only problem is that at the 2 year mark because of my endometriosis, I start to get really bad cramping."
