I had the same problem. I've had mine out for a little over two weeks now, and I've not had the pain during sex like I did with the Mirena. Another poster said that pain could be due to the irritation/inflamation that the Mirena can cause. Makes sense to me since it is a foreign object in there! But yeah, the abdominal stabbing pain---I had that in my lower left. But for the past two weeks--no problems!
