weight gain?

anyone on depo and breastfeeding still gain a lot of weight? I took the depo shot at my 6 week appointment and ever since i’ve been extremely hungry i’ve been eating everything in sight literally every 2-4 hrs like a baby and i’m snacking a ton even after meals.. i’m a skinny girl and i’d love to gain weight but I do not want to get huge. I know breastfeeding burns a lot of calories. with my first I dropped down super small while breastfeeding.
