period/spotting question

Alicia

I've had the mirena iud for about seven months now. I didn't get my period at all in December (although I still had cramping and even my boob's were sore), and then I got it early in January. still having some very light spotting and it's been over for a little over two weeks. anybody else have weird period/spotting experience with mirena? 🤔 thanks guys.
