Has anyone had seizures after getting the MIrena?

I am 29, and had my 2nd Mirena IUD inserted in January of this year (2012), because I had it before and loved it. Well On February 9th I had my first ever grand mal seizure and stopped breathing. I began spotting the next day. I had no period for March or April and then On May 10th at 2am, I had a grand mal seizure again and aspirated on my own vomit causing me to be intabated. I began spotting when I awoke around noon on the 10th. I am almost positive that the MIrena is the cause of my new seizure activity, can anyone else tell me if they have a similar story? Thanks.
