Skyla IUD and weight gain?

Does anyone have the Skyla IUD and have experienced weight gain? I got it after I had my second child, she was born in May of 2015 and I got it in October of the same year. When I got pregnant with my daughter I was at 124, and when I got the Skyla inserted 5 months after her birth I was about 145. Ever since I got it I have done nothing but gain weight. The heaviest I have gotten is 163 and is what I currently weigh. Has anyone else experienced weight gain with this IUD, or does anyone have opinions or suggestions On a type of birth control that doesn't cause weight gain?
