• Braxton Hicks contractions: These practice contractions may become more frequent and intense as your body gears up for the real thing.
• Pelvic pressure: As your baby descends further into your pelvis, you may feel increased pressure and discomfort in your pelvic area.
• Frequent urination: With your baby's head pressing against your bladder, you may find yourself making more trips to the bathroom.
• Mucus plug discharge: You may notice a thick, clear, or slightly bloody discharge, which is a sign that your cervix is beginning to dilate.

Baby’s Growth in the Womb

• Organ Development: By now, all of your baby's organs are fully formed and functional. Their lungs are mature and ready to take their first breath, while their digestive system is prepared to handle breast milk or formula.
• Physical Features: Your baby's physical features are well-defined, with a head full of hair, fingernails that extend past their fingertips, and toenails that have reached the end of their toes. They can blink, turn their head, and grasp with their hands.
• Weight of the Foetus: The average baby at 40 weeks weighs between 3.2 and 3.6 kg and measures about 50 cm in length. However, healthy babies can vary in size, with some weighing more or less than this average.
• Movement of the Baby: As your baby runs out of room in your uterus, you may notice a decrease in their movements. However, you should still feel them move regularly throughout the day. If you notice a significant decrease in movement or haven't felt your baby move for an extended period, contact your healthcare provider immediately.

Physiological Changes During Week 40 of Pregnancy

• Breast Changes: Your breasts may feel even fuller and heavier as they prepare for breastfeeding. You might notice colostrum, a yellowish fluid, leaking from your nipples.
• Hair, Skin, and Nails: Hormonal changes during pregnancy can cause your hair to appear thicker and more lustrous. However, some women experience hair loss postpartum as hormone levels return to normal. Your skin may feel stretched and itchy, especially around your belly, as it accommodates your growing baby.
• Respiratory and Cardiovascular System: You may find breathing easier as your baby moves further into your pelvis. However, due to the increased pressure on your diaphragm, you might experience shortness of breath or difficulty catching your breath.
• Vaginal Discharge: You may notice an increase in vaginal discharge, which can be clear, white, or slightly bloody. This is normal as your body prepares for labour. If you experience a sudden gush of fluid, it could be a sign that your water has broken, and you should contact your healthcare provider.
• Uterus Size and Position: Your uterus has expanded to accommodate your full-term baby, reaching up to your rib cage. As your baby descends into your pelvis, you may feel increased pressure and discomfort in your lower abdomen and pelvis.
• Placenta Position: The placenta continues to provide your baby with nutrients and oxygen until delivery. After your baby is born, the placenta will detach from the uterine wall and be delivered after birth.
   

• Ultrasound

While not always required, an ultrasound may be advised to assess your baby's position, size, and amniotic fluid levels. If the baby isn’t in the ideal head-down position, your doctor may discuss options like an external cephalic version (ECV).

• Cervical Exam

Your doctor will check for cervical dilation (opening) and effacement (thinning), key indicators of labour progress. They may also assess the baby’s station and how far they have moved into the pelvis.

• Non-Stress Test (NST)

This test tracks your baby’s heart rate in response to movements, ensuring they get enough oxygen. It’s commonly done if you’ve passed your due date or have concerns about fetal well-being.

• Biophysical Profile (BPP)

This test combines an ultrasound and NST to evaluate your baby’s breathing, movement, muscle tone, heart rate, and amniotic fluid levels. A low score may prompt closer monitoring or an early delivery.
