Mirena is a hormonal birth control IUD that uses progesterone, like the Depo Provera injection, or the mini pill. Taking progesterone over an extended length of time actually stops your extent - it's normal. I've be on Depo for almost three years and I don't get a time anymore. HOWEVER, from time to time, I DO spot. This, too, is normal. I'll spot for a few days, perchance a week at most, then it go away. I'd say this happen maybe once or twice a year for me.
