Is there a birth control that wont make you gain weight?

I currently use the depo shot and when I started using it I gained 50 lbs really fast. I've been using it for about 2 1/2 years and I can NOT loose weight, not even a pound. I am no longer gaining weight however. I have tried everything to loose weight, and nothing will work. so I need a new birth control that will allow me to loose all the weight I have gained since the depo shot. I would preferably want one that reduces or gets rid of my period like the depo does, and it does have to be something that is not daily. does anyone have any suggestions?
