Pregnant week 31 – the body takes up more space, the pace slows down

Pregnant week 31 is in the middle of the third trimester, when pregnancy is very noticeable in the body for many. The belly is big and heavy, the baby's movements are clear, and the need for breaks and consideration takes up more of your daily life. At the same time, the anticipation of the birth can begin to take up more of your mental space.

Week 31 is therefore often about accepting a slower pace and listening more closely to your body's signals.

What happens in the body at week 31?

In the 31st week of pregnancy, the uterus continues to grow and puts further pressure on the diaphragm and internal organs. This can cause shortness of breath, especially during activity or when lying on your back. The center of gravity is clearly shifted, and the strain on the back, pelvis and hips can be significant.

The blood volume in the body remains high and the circulation is working intensively. This can lead to swollen legs and feet, sensations of heat and the need to rest with the legs elevated.

Symptoms in pregnancy week 31

Many pregnant women experience persistent fatigue and reduced physical energy during the 31st week of pregnancy. Sleep may be challenged by the stomach, the baby's movements, labor pains or frequent toilet visits. Heartburn, indigestion and abdominal pressure are common symptoms.

Contractions may occur frequently and be more pronounced than before. They are usually irregular and subside with rest, but may require you to slow down.

What happens to the baby at week 31?

In the 31st week of pregnancy, the baby is about 41–42 centimeters long and weighs approximately 1,600–1,700 grams. The baby continues to grow rapidly and gain weight. The subcutaneous fat increases, which is important for temperature regulation after birth.

The brain continues to develop at a rapid pace and the nervous system becomes more mature. The baby can respond clearly to sounds, light and touch, and movements are powerful but more limited by the space in the womb.

Pregnant week 31 and movements

For most people, week 31 of pregnancy is marked by daily and clear movements. Kicks, rolling and stretching can be clearly felt, but may feel slower and more pushing than before due to lack of space.

It is important to continue to feel life on a daily basis. If you experience clear changes in your movement patterns, you should react and contact healthcare professionals.

Pregnant week 31 and the belly

At week 31, most people's stomachs are very large. The uterus is high, and the stomach can feel tight, heavy, and tense. This can significantly affect balance, mobility, and comfort in everyday life.

Many people experience a need for extra support in the form of rest, pillows and adaptation of daily activities.

What can you do in week 31?

Pregnancy week 31 is a good time to prioritize recovery and relief. Breaks during the day, good sleeping positions, and support for the back and pelvis can make a big difference. Light movement can still be beneficial if it feels good and does not cause discomfort.

During this period, many people also begin to focus more on the final preparations for birth and postpartum.

Thoughts and feelings in pregnancy week 31

When the body takes on more volume, it can affect both mood and energy. Anticipation for the birth can grow, but it can also give rise to worries or a need for reassurance and preparation.

All of these feelings are normal and part of the transition towards birth.

When should you seek medical attention?

In the 31st week of pregnancy, there is generally no need for emergency medical care. If you experience regular painful contractions, persistent abdominal pain, bleeding, fever, sudden severe swelling or significant changes in the baby's movements, you should contact your doctor or midwife.
