copper Iud maybe moved???

I got my paraguard Iud inserted back in March and have had no problems with it since.   
My period just ended a couple of days ago and I have brown discharge (probably just old blood) but I went to check my strings like usual and my Iud strings usually feel coiled and kind of short, this time they felt coiled still but longer.  I'm just hoping that my Iud didn't get displaced.....
