Week 31 of Pregnancy

Pregnancy Week 31 continues to bring rapid growth, as your baby's senses become fully functional and movements grow stronger. Healthcare providers calculate pregnancy from the first day of your last menstrual period, and by week 31 your baby is often compared to the size of a coconut or a large pineapple.

Understanding week 31 of pregnancy can help you know what is happening in your body as you continue progressing through the final trimester.

What Happens During Week 31 of Pregnancy?

During week 31, all five of your baby's senses, including sight, hearing, taste, touch and smell, are now functioning. Your baby also continues gaining weight rapidly as fat stores increase.

As space in the womb becomes more limited, movements may feel different, though your baby should continue moving regularly.

What Are the Symptoms of Pregnancy in Week 31?

Pregnancy symptoms in week 31 often reflect a growing bump and continued changes in circulation and comfort.

• Braxton Hicks Contractions

Mild, irregular tightening of the uterus can become more noticeable during this stage.

• Backache

As your bump continues to grow, mild back discomfort can persist.

• Pelvic Pressure

As your baby grows and moves lower, some people begin to notice increased pressure in the pelvic area.

• Increasing Fatigue

Tiredness often continues as your body works harder to support your growing baby.

• Swollen Feet or Ankles

Increased blood volume and fluid retention can continue to lead to mild swelling in the feet or ankles.

What Should You Eat During Week 31 of Pregnancy?

A nutrient-dense diet remains important in week 31, especially as your baby continues gaining weight rapidly.

• Choose Healthy Fats

Foods such as avocados, nuts and olive oil support your baby's rapidly increasing fat stores.

• Choose Iron-Rich Foods

Iron supports your rising blood volume and helps prevent fatigue. Good sources include lean meat, beans, chickpeas, lentils and spinach.

• Include Protein in Your Diet

Protein supports your baby's rapidly developing organs and tissues. Eggs, fish, chicken, paneer, tofu, beans and lentils are useful sources.

• Choose Fibre-Rich Foods

Fibre from fruits, vegetables and whole grains can help support digestion during this stage.

• Stay Hydrated

Adequate water intake can help ease swelling and support increasing blood volume.

What Foods and Substances Should You Avoid?

As your baby continues gaining weight and developing rapidly, avoiding certain substances and foods remains an important part of a healthy pregnancy.

• Alcohol and Tobacco

Avoid alcohol and smoking completely, as they can affect your baby's developing brain and organs.

• Excessive Caffeine

Keep caffeine intake within the limits recommended by your healthcare provider.

• Raw or Undercooked Foods

Choose properly cooked foods and follow good food-safety practices, avoiding raw or undercooked meat, eggs, unpasteurised dairy and high-mercury fish.

• Highly Processed Foods

Limit foods high in added sugars, excess salt and unhealthy fats, and focus instead on a varied, nutrient-rich diet.

Exercise During Week 31 of Pregnancy

Gentle movement can help ease pelvic pressure and support circulation, though it is important to listen to your body and rest when needed.

Choose activities that are comfortable for your fitness level, and avoid suddenly starting strenuous exercise without appropriate guidance.

• Walking and Gentle Exercise

Walking is a simple, low-impact way to stay active and can help support circulation and mood.

• Stretching and Yoga

Gentle stretching and suitable prenatal yoga practices can support flexibility, relaxation and help ease pelvic pressure.

How Can You Prepare for a Healthy Pregnancy?

Week 31 is a good time to continue preparing for birth and staying attentive to your baby's movements.

• Continue Tracking Fetal Movement - Pay attention to your baby's regular patterns of movement, and mention any noticeable changes to your provider.

Regular check-ups continue to monitor your health and your baby's growth, often occurring every two weeks.

Routine monitoring continues to track your overall health throughout the third trimester.
