Skyla IUD moved


I have had my Skyla IUD for a year and half now. I have been having the sharp pain down by my pelvic, it felt like knifes stabbing me constantly. So went to my OBGYN and had some test run come to find out my IUD has moved downwards and he thinks I might need to remove it. I’m not sure if I should or wait til my 3 years are up. Has anyone have any problem with the IUD moving?
