Bloody Discharge After Rough Sex IUD

I have the Mirena IUD and I've had this issue in the past but this time it is lasting a little longer than usual. I had some rough intercourse recently and I've been having cramps and bloody discharge. It's only the second day since I had sex and I've bled before if the guy got too deep, but I am just wondering if this is bad or normal and if it happens for anyone else. It doesn't smell or itch so I'm assuming it's just from the fun we had and not an infection. Comments please!!!
