Mirena help

Shannon
So, I've had my IUD (Mirena) for about a year now. At first, my period was a bit irregular. It stopped altogether, and I didn't have another period for 10 months. But now, I'm starting to get bleeding and cramps again. I went to my OBGYN and had an internal ultrasound. Nothing was out of place or wrong, but I was wondering if anyone else had a similar issue with their IUD.
