Weight Loss

Okay ladies so last year January 2015, I started the Depo Shot. From January Until September I remained on the depo until I switched to the Nuva Ring for a month in October. Then Novemeber 11 2015 I got my mirena inserted. I've gained weight since then but I've also haven't been exercising the best or eating. Has anyone experienced weight loss with the mirena and what did you do to lose the weight? What can I do to maximize weight loss with the mirena? Also any tips provided would be greatly appreciated.
