Weight gain with Mirena?

I've had Mirena for five years now. Over that time I've gained about 50 pounds. I know weight gain is not listed as a side effect, but I'm a little skeptical. I feel like the only way to test my theory is to remove it and not be on any hormonal birth control for some time. At the same time, I love the peace of mind that it gives me (not worried about getting pregnant) and how it made my periods lighter and shorter. I'm not saying Mirena was the reason I gained weight, but I believe it's a possibility. Right now I'm debating on whether I should keep it, replace it with a copper IUD or go without any birth control for a little bit. If you have or have had Mirena for at least a year, I would love to know your experience, especially in regards to weight (maintained, lost or gained).
