Now that you're in the third trimester, you might experience more noticeable symptoms as your baby grows. While some of these symptoms may be uncomfortable, they are all part of the natural changes happening in your body.

Increased Baby Movements

You will likely feel your baby moving more frequently, and their movements may become stronger and more defined.

Back Pain

As your uterus grows, it can place more strain on your back, causing discomfort.

Shortness of Breath

The expanding uterus continues to pressure your diaphragm, making breathing more difficult.

Heartburn and Indigestion

Your growing baby pushes against your stomach, which can lead to heartburn or indigestion.

Swollen Feet and Ankles

Fluid retention can cause swelling, especially in your lower legs and feet.

Stretch Marks

The stretching skin on your abdomen may lead to stretch marks, which are common during pregnancy.

Fatigue

You may feel tired as your body works hard to support your pregnancy.

Frequent Urination

Your growing uterus puts pressure on your bladder, causing you to urinate more frequently.

Varicose Veins

Pregnancy hormones and increased blood volume can cause varicose veins to appear, especially in your legs.

Tracking these symptoms can help you better understand what to expect and when to seek advice. Contact your doctor if you have concerns about any unusual or severe symptoms.

Baby’s Growth in the Womb

Organ Development

Your baby’s lungs are maturing and producing more surfactant, which will help their lungs expand and function after birth. The brain is also continuing to grow and become more sophisticated.

Physical Features

Your baby’s skin is thickening, and they are developing a layer of fat underneath them, which will help keep them warm after birth. They now have fully formed eyelids and can open their eyes. Your baby’s hearing is becoming more refined. They can now hear your voice and the sounds around them more clearly.

Weight of the Foetus

At 27 weeks, your baby weighs about 875 grams and will continue to gain weight as it prepares for birth. Your baby is about the size of a head of cauliflower, measuring around 40 cm in length.

Movement of the Baby

Your baby is becoming more active, and you may feel strong kicks and movements as their muscle coordination improves. You will likely feel more distinct movements, including kicks, rolls, and stretches. The baby’s nervous system is developing and may respond to light and sounds from the outside world.

Physiological Changes During Week 27 of Pregnancy

Breasts

Your breasts may continue to grow and become more tender. Some women begin to leak colostrum, the first milk to nourish your baby after birth.

Skin, Hair, and Nails

Hormonal changes affect skin, hair, and nails. You may notice a thickening of your hair. Still, some women also experience changes in skin pigmentation, such as darkening of the areolas or a dark line running down their belly (linea nigra).

Respiratory and Cardiovascular Systems

As your uterus grows, it may press on your diaphragm, making breathing harder to breathe deeply. Shortness of breath is common at this stage.

Leg Oedema

Increased blood volume and the pressure from your growing uterus can cause swelling in your legs, ankles, and feet. Elevate your feet and avoid standing for long periods.

Uterus and Cervical Position

Your uterus expands rapidly as your baby grows. You may experience more frequent Braxton Hicks contractions as your body prepares for labour.

Vaginal Discharge

Increased discharge is normal. It should be clear or milky and odourless. However, if you notice any changes in colour, consistency, or smell, contact your doctor.
