Bleeding with Mirena

Katelyn

I got Mirena put in about a week ago. I had Skyla and just got it swapped out to Mirena. I was on the last day of my period when I switched it out. I spotted that day, had some mild cramping, overall it wasn’t awful. I stopped spotting for a couple days, and now I’m bleeding. More than what I would consider to be spotting, but it’s old brown blood. Is this normal? Has anyone else had an experience like this?
