I am strongly considering an IUD. I was leaning toward the Paragard because I liked the idea of "no hormones," but after reading other IUD-related threads, I am a little nervous about the reports of extreme bleeding. I would appreciate hearing from others who have tried either the Paragard or Mirena IUD. If you have or have had a Mirena, did you experience any negative side effects that you attribute to the hormone it releases? TIA!
