Paraguard problems please help

Kate

I got paraguard 18 days ago. Since then, it's been hell "down there." First, it kick started my period the moment I woke up from anesthesia and was in the most excruciating pain I think I've ever been in my entire life. And that's after having broken my neck, believe me this was worse. I couldn't walk for 2 days without fainting. I couldn't eat or move or anything!!! Now, it hurts to pee so bad and it's been like this for at least 3 days. I don't understand. Please please please help me figure out what's going on.
