 Maternal Breast Tissue- 1 to 2 pounds

 Maternal Blood Volume- 3 to 4 pounds

 Maternal Fat and Protein Storage- 8 to 10 pounds

 Other Body Fluids- 3 to 4 pounds

 Baby- 6 to 8 pounds

 Placenta- 1 to 2 pounds

 Uterus- 1 to 2 pounds

 Amniotic Fluid- 2 to 3 pounds

Work Out Your Desired Pregnancy Weight

First, Compute for your Basal Mass Index or BMI. This can be done by getting the square of your height in meters and dividing it by your weight.

Secondly, know the recommended weight gain for your BMI and check the recommended total weight gain for the corresponding BMI.

Weight Gain Tracker and Weight Gain Chart by CDC


• Write your pre-pregnancy weight in the space provided.

• Based on your week of pregnancy* , write the date and your weight that is rounded
off to the nearest pound.

• Write today’s weight gain in the space provided on the weight gain tracker. To determine today’s weight gain, subtract your weight just before pregnancy from today’s weight.
Example: subtract your weight just before pregnancy (130 pounds) from today’s weight (135 pounds) to determine today’s weight gain (5 pounds).

• Print the chart and plot your weight gain in the graph by putting an “x” in the corresponding week and weight gain.

• The shaded area corresponds to the normal weight gain for pregnant women,and if your graph is outside of the shaded area, it means that you should make adjustments to your weight gain and exercise.

• Leave a blank space for your missed week and continue plotting on the chart/graph until your 40th week

Importance of Gaining Weight Within the Normal Range

It is important to gain weight within the normal range, to refrain from delivering a too-small-for-gestational-age baby because of insufficient nourishment for the fetus. Babies that are born too small may have difficulty in feeding and may have developmental delays.

Gaining more than the recommended weight range can lead to a big baby that will eventually cause the mom to undergo cesarean section and obesity.
