Normal or not normal ?

So I have had the IUD for about 2 1/2 years and randomly I didn't get my period for 2 months after it being regular. And then I got a very light light period (I think) a few days ago and it's so light that i don't even need to use anything. It's been like this for 3 days tho. Is this normal ? It's kinda more like a heavy discharge and someone's it's got a color to it.
