I am so sorry for your situation and your loss.  Yes, I would speak with an attorney that deals with medical issues in your area as soon as you can.  The consultation should be free and it will give you a good idea as to whether or not you have a case. There are certain risks associated with the IUD, which had to be properly explained in some way to you, in conjunction with your state law.  There also has to proven causation between the IUD and the infection (i.e., did it cause it) and the infection and the miscarriage.  And of course, injury and resulting damages.  Good luck with everything.
