Pregnant week 27 – the transition to the third trimester

Week 27 of pregnancy marks the transition to the third trimester. For many, it feels like a clear milestone as pregnancy enters its final and most physical phase. The belly is big, the baby's movements are strong, and the body may begin to require more rest and attention than before.

Week 27 can therefore be characterized by both anticipation and the need to slow down.

What happens in the body at week 27?

At 27 weeks pregnant, your uterus continues to grow and now fills a large part of your abdominal cavity. This can put pressure on your diaphragm and make breathing more shallow, especially when you are lying down or physically active. Your center of gravity has changed significantly, which can put additional strain on your back, pelvis, and hips.

The body's circulation continues to work intensively, and the increased blood volume can cause swollen legs and feet, sensations of heat, and faster fatigue.

Symptoms in pregnancy week 27

Many women experience more physical symptoms at 27 weeks pregnant. Fatigue can be severe, and sleep can be affected by the stomach, the baby's movements, and frequent toilet visits. Heartburn, indigestion, and shortness of breath are common symptoms.

Contractions may occur more frequently and be more pronounced, especially during activity or at the end of the day. They usually subside with rest.

What happens to the baby at week 27?

At 27 weeks pregnant, the baby is about 35–36 centimeters long and weighs approximately 900–1,000 grams. The baby is growing rapidly and begins to gain more subcutaneous fat, which is important for temperature regulation after birth.

The lungs are still developing, and the baby is practicing breathing by inhaling amniotic fluid. The brain is developing rapidly, and the baby can respond more clearly to light, sounds, and touch.

Pregnant week 27 and movements

For most people, week 27 of pregnancy is a week of very clear and strong movements. Kicks and rolling can be noticeable and sometimes uncomfortable. The movement pattern may start to become more recognizable, although variation is still normal.

Many people are now starting to pay more attention to their baby's periods of activity throughout the day.

Pregnant week 27 and the belly

At week 27, the belly is large and clearly pregnant. The uterus is high, and the belly may feel heavy and tense. This can affect both balance and mobility and make it necessary to move more carefully in everyday life.

The need for comfort, support, and breaks often becomes more pronounced during this phase.

What can you do in week 27?

Pregnancy week 27 is a good time to prioritize rest and relaxation. Taking breaks during the day, supporting your back and pelvis, and sleeping in good positions can make a big difference. Light exercise can still be beneficial if it feels good and doesn't cause discomfort.

Many are also beginning to take a more active approach to birth preparation and practical preparations for the last part of pregnancy.

Thoughts and feelings in pregnancy week 27

The transition into the third trimester can bring up many emotions. Anticipation can grow, but it can also make pregnancy more real and therefore more vulnerable. It's completely normal to think more about the birth and the time after.

There is room for both joy, worry and reflection.

When should you seek medical attention?

In the 27th week of pregnancy, there is generally no need for emergency medical care. However, if you experience regular painful contractions, persistent abdominal pain, bleeding, fever or sudden changes that worry you, you should contact your doctor or midwife.
