Hi N.,
This is my second time with Mirena. I had this one inserted at my 6 week postpartum check-up and my son is still breast-feeding at 8 months. It seemed as though my postpartum bleeding was prolonged a bit with the Mirena but I haven't had any spotting or periods since the postpartum bleeding stopped. With my first son I didn't get my period back until he was 7-8 months or so, roughly 2 months after I stopped breast-feeding. Also, the first time I had the Mirena (got it when my second son was about 2 1/2 and had it for a little over a year and a half or so) I had the spotting/bleeding for a few weeks after insertion then nothing until I had it removed.
Good luck with it all,
A.
