Mirena
"I had paraguard for four years and experienced very bad cramps during ovulation and my period, along with heavy bleeding.  I switched to Mirena after consulting with a new GYN.   The removal of paraguard was painless and took less than a second.  The original insertion of it was extremly painful.  I had it inserted when I was in my late 20s, no children.  I still have no children and found the insertion of the Mirena to be no worse than two bad cramps, each lasting only a second.  I took 800mg of Motrin about an hour prior to the precedure, which may have helped.  I had no cramping or spotting after the procedure and have still have no cramping or spotting."
