Mirena IUD period

Elizabeth • Nurse & mama to 1🥰

So I'm on a regular cycle these past few months and I've had my Mirena for 6 months. My periods used to be clotty, heavy, crampy messes but they have been lighter and no cramps! I started my period today and it is definitely lighter than when I didn't have the IUD but heavier than previous periods.

This period has also been more crampy than usual too. Is this normal or should I get it checked?
