You can't know that in advance. You can weigh yourself now, and again after some days or weeks, to see whether you have gained or lost weight.
Take the dog to the vet, or call the vet for any recipes of homemade dog food that could help it gain weight.

Normal weight gain depends on your weight before pregnancy. If you are underweight you should gain 35 lbs, normal weight you should gain 25 lbs and if you are overweight you should gain 15 lbs. By 19 weeks you should have gained around 1/3 of the appropriate amount for you size.
