Gaining some fat deposits when you're pregnant is normal and actually necessary! Gradual weight gain isn't linear weight gain. In other words, you may gain 3 pounds in one week and none for the next few weeks. As long as you're trending a steady weight gain, don't worry if you find that you gain more in one week and less in others. (Some women even lose a pound or two occasionally throughout their pregnancy.)
As long as the overall trend is that you're gaining weight (slowly and steadily, of course), don't stress out about the exact number on the scale.The amount of weight you should gain during your pregnancy is based on your pre-pregnancy weight status, or body mass index (BMI):
Body Mass Index | Recommended Weight Gain |
Less than 18.5 (underweight) | 28 to 40 pounds (12.5 to 18 kilograms) |
18.5 to 24.9 (normal weight) | 25 to 35 pounds (11.5 to 16 kilograms) |
25 to 29.9 (overweight) | 15 to 25 pounds (7 to 11.5 kilograms) |
30 or more (obese) | 15 pounds (7 kilograms) or less |
To prevent excess weight gain and to keep your heart, lungs, and muscles strong, exercise throughout your pregnancy. In particular, aim for a mix of aerobic exercise, strength training, and yoga.
