Your weight gain during pregnancy is directly affected by your weight before pregnancy. I’m going to be writing about weight in four categories: Underweight, Normal Weight, Overweight, or Obese. These categories are each determined by your Body Mass Index (BMI). You can use
this website’s calculator here to figure it out if you aren’t sure. If you were underweight before pregnancy, it is recommended you gain more. And of course, if you were overweight before your pregnancy began, you are going to aim to gain less.
