my mom had it and bled for over 15 days, then got it taken out and got a different brand , then that one just hurt her really bad and gave her horrible cramps for about a week to where she was in tears all the time, then she went back again and they told her it had shifted and now she had a uti from it & my mom was kinda like "I haven't done anything for it to move it was your guys fault" (cuz it's supposed to stay in place during sex and working out or anything you do) and threatened to sue them & they gave her the money back and took it out for free.
