Hi Dianna, 
You need more food, plain and simple, you are not getting enough and your body will not let the pounds go until you do. 
Breakfast-Endure or Slimfast shake/Coffee and water after one hour 
Lunch-left over meat, veggies 
Snack-bran bar, unsweetened pudding, apple slices...try to avoid refined sugars in your snickers...although they are only 35 calories..it's pure sugar which converts directly to fat. 
Dinner-protein, veggies, rice or potato 
Snack-fruit, nuts, cheese 
Try this and see what happens..you are doing great with your exercise and water, but baby you need to eat more!!! 
Good Luck!!!
