pill weight gain

hey everyone! i gained about 30lbs this year from the Layolis Fe (Generess) pill. I’m off of it now due to that and severe depression and migraines. I’m on the Mirena now as of Wednesday, and I’ve read many stories about weight gain with different birth controls but has anybody had a success story with LOSING weight while on these drugs? I’m really just looking for any answers, as it’s effecting my self-esteem. So far, working out/dietary isn’t helping. Vitamins? Specific regimens? Thank you guys :)
