Really wish i could go back to my original size😢

JA`s Mommy👶💙
Prepregnancy I was 140lbs and now I'm 159lbs. Its been weeks since dieting and excersing and no progress yet. I would love to be at 130lbs. I miss my cute belly button that I use to have! Now its all flappy and stretchy. And it feels like its going to take forever to get there😢. Any suggestions? Or anyone in the same boat?
