31 Weeks Pregnant

At 31 weeks pregnant, you’re in your third trimester and are approximately seven and a half months pregnant. This is a significant milestone in the pregnancy because your baby continues to grow and develop rapidly and is gaining weight faster.

In this article, we’ve got plenty of information about pregnancy week 31, from symptom management to self-care tips to common FAQs about this exciting stage of your pregnancy journey. Let’s look at your baby’s development by pregnancy week 31.

Your baby’s development at 31 weeks pregnant

At 31 weeks pregnant, the baby has already undergone significant development, but some critical milestones are still happening during this pregnancy stage.

Your baby is around 16.2 inches (41.1 cm) in length and weighs approximately 3.3 pounds (1.5 kg). That’s about the size of a coconut!

Here are some of the key baby development milestones that are typically reached around 31 weeks:

Pregnancy Nutrition Course

1. Increased rate of growth

At this stage of pregnancy, the baby is growing and gaining weight faster than earlier in the pregnancy.

2. Developing fat

The baby is beginning to accumulate fat, which will help regulate the baby’s body temperature and provide a source of energy after birth.

3. Developing lungs

The baby’s lungs continue to mature, and the baby is practicing breathing movements.

4. Developing senses

The baby’s senses continue to develop, and the baby may be able to see the light and distinguish between different tastes and smells.

5. Developing brain and nervous system

Baby’s brain and nervous system continue to develop, and they can process information and move in response to stimuli.

6. Developing sleep-wake cycle

The baby is beginning to develop a regular sleep-wake cycle, which may mean that the baby is more active at certain times of the day. You should easily feel your baby’s movements when they’re active.

7. Protective and nourishing amniotic fluid

At 31 weeks, the volume of amniotic fluid in the uterus is at its highest point, providing a protective cushion for the growing baby while facilitating the exchange of nutrients and waste products between the baby and the placenta.

Overall, at 31 weeks pregnant, the baby is nearing the end of development and is getting ready for life outside the womb.

Dealing with pregnancy symptoms at week 31

At 31 weeks pregnant, it’s common to experience various symptoms. These symptoms are normal but can be challenging nonetheless. 

Here are some common symptoms and tips to help you deal with them:

1. Swelling

Swelling of the ankles, feet, and hands is common during pregnancy. 

To minimize swelling, try to stay off your feet as much as possible, elevate your feet when you sit down, and avoid standing or sitting for long periods. This will also help you reduce the onset of pregnancy-related stretch marks.

2. Fatigue

As your body prepares for the baby’s arrival, you may feel more tired than usual. Make sure to get plenty of rest and take breaks throughout the day.

3. Frequent urination

Frequent urination is a common symptom during pregnancy, especially in the later stages. It occurs when the growing uterus puts pressure on the bladder, causing you to go to the bathroom more frequently. 

To deal with frequent urination at 31 weeks pregnant, staying hydrated and being mindful of your fluid intake is important. Try to avoid drinking too much fluids in the evening or before bedtime.

4. Trouble sleeping

Trouble sleeping is common during pregnancy, especially in the later stages. 

To deal with trouble sleeping at 31 weeks pregnant, try establishing a relaxing bedtime routine, sleeping on your side with pillows for support, avoiding caffeine and heavy meals before bed, and creating a comfortable sleep environment. 

If the problem persists, talk to your healthcare provider for additional guidance.

5. Braxton Hicks contractions

These are practice contractions that can happen anytime during the third trimester. They can be uncomfortable but are usually not painful. Try changing positions, drinking water, or taking a warm bath to ease the discomfort.

6. Back pain

As your baby grows, your back may begin to ache. Practice good posture, wear comfortable shoes, and consider a pregnancy pillow to support your back as you sleep.

7. Heartburn

Many women experience heartburn during pregnancy. To alleviate symptoms, avoid spicy and acidic foods, eat smaller meals more frequently, and avoid lying down right after eating.

Talking to your healthcare provider if your concerns or symptoms are severe or persistent is important.

Is walking good at 31 weeks pregnant?

However, talking to your healthcare provider before starting or continuing any exercise routine during pregnancy is important, especially if you have any underlying health conditions or complications.

Your healthcare provider may also recommend modifying your exercise routine as your pregnancy progresses. For example, you may need to adjust your walks’ intensity, duration, or frequency as your baby grows and your body changes.

Can unborn babies sense their father?

Some studies suggest that unborn babies can recognize and respond to familiar voices, including their fathers. 

For example, research has shown that unborn babies may move or react differently in response to their father’s voice than a stranger’s. This suggests they can distinguish between different voices and respond to them meaningfully.

Additionally, some studies have suggested that fathers actively involved in their partner’s pregnancy, such as by talking to the baby or rubbing their partner’s belly, may have a stronger bond with their baby after birth.

Fathers can play an important role in prenatal development and bonding; unborn babies can sense and respond to their father’s presence in various ways.

What position is a baby in at 31 weeks?

At 31 weeks pregnant, the baby is typically in a head-down position, the optimal position for a vaginal delivery. This position is also known as the cephalic presentation.

However, it’s important to note that not all babies will be in a head-down position at 31 weeks. Some babies may still be in a breech position, meaning their buttocks or feet are positioned to be delivered first. 

If your baby is still in a breech position at 31 weeks, it is time to turn into a head-down position before delivery. 

However, a cesarean section may be necessary if your baby remains in a breech position at delivery.

Note that some babies may move in and out of different positions throughout the day, especially during the earlier stages of pregnancy. 

As the baby grows and runs out of space in the womb, it will be less likely to change positions frequently. 

However, it’s always best to consult your healthcare provider if you have concerns about your baby’s position or movement patterns.

Do I have breast milk at 31 weeks pregnant?

At 31 weeks pregnant, your body prepares for breastfeeding by producing colostrum, a nutrient-rich pre-milk substance that will help nourish your baby in the first few days after birth.


Congratulations on reaching 31 weeks of pregnancy! At this stage, your baby is continuing to grow and develop rapidly, and you may be starting to experience some of the typical discomforts of late pregnancy. 

However, there are many things you can do to support your health and the health of your developing baby, such as staying active, eating a healthy and balanced diet, and getting plenty of rest.

Remember to take good care of yourself during this time and to seek support and guidance from your healthcare provider if you have any concerns or questions about your pregnancy. 

With proper care and attention, you and your baby will be on your way to a safe and healthy delivery.
