"i went to have the mirena iud removed 1 1/2 years after placement and my ob/gyn couldn&#039;t find it to remove it. i have had an ultrasound that turned up nothing and now need an abdominal xray to see if it can be located that way. my insurance won&#039;t cover any of it until my deductible is met,  so i have to come up with $1000 just to find out, and if they find it, i&#039;ll need surgery. this &quot;migration and spontaneous expulsion&quot; are more common than the company says.
