What is the third trimester?

The last leg of the pregnancy or Week 27 to end of pregnancy is termed as the third trimester of pregnancy. For some women this can be week 36, while for others it may be less or more.

Third trimester pregnancy symptoms

In the last trimester, your body grows to accommodate the full-grown baby and prepare for birth. This is the time you will notice many changes like below:

Braxton Hicks Contractions

Braxton Hicks contractions are mild, irregular contractions that can be felt as a tightening in your lower abdomen. Occurring generally after physical activity or sex, these subside by themselves and also take place in the second trimester. Contact your doctor if they become regular and more severe.


Your body is now fully grown as a home for the new baby and as your baby grows and prepares for birth, you will notice fatigue and shortness of breath. Take frequent breaks and get ample rest. Also find a good posture at all times, to avoid putting pressure on your lungs.

Frequent urination

As your baby moves lower into your abdomen, you will feel extra pressure on your bladder and the frequent urge to pee. You may also notice urine leaking when you sneeze or laugh too hard. If the leakage is thicker or coloured, contact your doctor immediately.

Hemorrhoids and Varicose veins

In your third trimester of pregnancy, your body is pumping extra blood which may cause your veins to become prominent as red or purple veins. Also known as spider veins, you may notice them in your neck and hands. Noticing swollen veins in your legs at this time, also known as varicose veins is also common. Hemorrhoids are also very common in the third trimester and doctors can prescribe medicines as well as natural remedies to ease the pain.

Heartburn and indigestion

Pregnancy hormones cause stomach acid reflux leading to heartburn - this can be controlled with eating small meals, avoiding fried and spicy food and sipping on digestive tea.


As your belly pulls your body forward, noticing back pains (Ranging from mild to severe) is pretty common in the third trimester. Look for comfortable positions and use proper support to alleviate the pain.


Marks Your body has grown and nourished a baby and your skin is stretching to do the same - noticing stretch marks is very usual at this stage and can be reduced with proper moisturization.

Psychological changes during third trimester of pregnancy

As the day to deliver your baby gets closer, your hormones also do the work and the natural anxieties about labour kick in at the time. Here are the psychological changes during third trimester of pregnancy that you may notice:

  • Fear and anxiety about the labour and delivery is a common occurrence - talk to loved ones and people who have positive stories to share for some reassurance
