When Do You Start Gaining Weight During Pregnancy?

Every woman will experience weight gain differently during their pregnancy, but most women can expect to gain 1 to 5 pounds during the first trimester, and then average a weight gain of 1 pound per week for the rest of your pregnancy.

You most likely won’t notice a significant weight gain straight away, as most women do not find out they are pregnant until far into the first trimester. However, once you confirm your pregnancy, you can start tracking your weight and will more than likely notice a slight weight gain as the weeks go by.

Work Out Your Desired Pregnancy Weight

To work out your desired pregnancy weight gain, you should calculate 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.

Pregnancy weight tracker

It is fairly simple to track your pregnancy weight gain at home, and it can be a useful tool to help your medical professional to use during checkups. 

Use the below table to help you track your pregnancy weight gain through each week in your pregnancy. This will help you determine if you are averaging a normal weight gain, or if you are below or above the normal.

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

Recommended Weight Gain Per Trimester for Single Pregnancy

Many women are left asking how much weight is normal to gain during pregnancy. Some women seem to remain so small, while others tend to put on weight easily.

Below is a guide on how much weight you should expect to gain during pregnancy, but it is important to remember that as long as you and your baby are healthy and have regular check-ups from a medical doctor, there should be nothing to worry about.


There is minimal weight gain during the 1st trimester, about 0.5 to 2 kilograms or 1.1 to 4.4 pounds. It is common to lose a significant amount of weight but make sure that it is not more than 5 to 10 percent of your pre-pregnancy weight, as this might be harmful to the baby.


During the 2nd trimester, your weight gain should be steady and gradually increasing with an average of 0.2 to 0.5 kilograms (0.5 to 1 pound) per week.


Until the 3rd trimester, your weight should continue to gradually increase/ The average weight gain during this time is around 0.2 to 0.5 kilograms 0.5 to 1 pound) per week, the same as during the 2nd trimester.

Recommended Amount of Calories Per Day

A healthy pregnancy does not only include exercise but also a balanced, nutrient-rich diet. Knowing the right number of calories that should be consumed per day can help you eat healthier. Here’s the normal number of calories that should be consumed per day for the whole duration of pregnancy.

  • First Trimester – 1,800 calories per day
  • Second Trimester – 2,200 calories per day
  • Third Trimester – 2,400 calories per day

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.

Babies who are born underweight also have a hard time breastfeeding. They might not be strong enough to suckle and latch for extended periods, and this could have a negative effect on your milk supply in the beginning, which could lead to problems breastfeeding in the future.

Gaining Too Much Weight During Pregnancy

While gaining too little weight during pregnancy can have health risks, gaining too much weight during pregnancy can also have some negatives effects.

Too much weight gained during pregnancy can cause health issues for both baby and mother. If a woman gains too much excess weight, there is a higher risk that her baby will be born too large. During labor, this can lead to vaginal tears and the need for a Caesarean section, and later on in life, it can contribute to obesity in the child.

After birth, excess weight gain can be difficult for the mother to lose, and this might also be a contributing factor to obesity in the mother herself, which can pose many health issues.

Not all women experience pregnancy symptoms, but those who gain excessive weight during pregnancy are more likely to suffer from achy joints, varicose veins, and heartburn. The extra weight puts additional pressure on your body, making it more difficult for blood and fluids to flow. This decrease in circulation can lead to hemorrhoids, leg cramps, physical exhaustion, and backaches.

Keeping a count on your pregnancy weight gain using a tracker is a great way to ensure you stay ahead of what is healthy and what might cause issues for both you and your baby, during pregnancy and well after birth.

Rapid Weight Gain During Pregnancy

Rapid weight gain during pregnancy is more prominent among women who were overweight before falling pregnant. If you find that you are gaining weight rapidly during pregnancy, speak to your health professional and try to adjust your diet, while still having all the nutrients you need, to stop excessive weight gain.

Gaining weight too fast in pregnancy can lead to health problems for mothers, who will more than likely suffer from backache, heartburn, and cramps. This might also pose a problem if the baby is gaining weight too quickly as well. 

How To Control Weight Gain During Pregnancy

You should only worry about controlling your weight gain during pregnancy if you are putting on weight rapidly. Without having to go through drastic changes, there are some ways to try and control your weight safely.


Be sure to get the go-ahead from your medical practitioner before exercising during pregnancy, but for most women, exercising is a good way to keep active, improve pregnancy symptoms and help to lose weight. 

Moderate exercise can be done a few times a week to help burn off extra calories. This does not need to be a tough workout routine, but many exercises are safe for pregnant women to practice. 

Keeping active by walking or swimming is a great way to keep extra weight off during pregnancy. It is low-stress on the body, it improves moods and works towards keeping the excess weight down.

Exercising during pregnancy has many benefits for both mom and baby, but be sure to speak to your doctor to make sure it is safe for you to exercise, and try to keep a light exercise routine throughout your pregnancy. 

Many workout programs designed for women not only help to keep weight down, but they strengthen the body in preparation for childbirth. A woman who exercised during pregnancy is more likely to have an easier labor and a quicker recovery post-birth.
