• Pelvic Pressure and Discomfort: As your baby moves into the pelvis, you may feel increased pressure and discomfort, a natural part of your body getting ready for labour.

• Braxton Hicks Contractions: These practice contractions become more frequent and intense, helping your uterus get ready for the real thing.
• Increased Vaginal Discharge: You may notice more discharge, sometimes with a pinkish or bloody tinge, as your mucus plug is released—a sign that labour could be imminent.
• Difficulty Sleeping: Physical discomfort and the excitement of meeting your baby soon can make restful sleep a challenge during these final weeks.
• Mood Swings and Emotions: Hormonal changes and anticipation of childbirth may lead to emotional ups and downs, which are completely normal at this stage.

Baby’s Growth in the Womb

• Organ Development: Although most of your baby's organs are fully developed, the lungs and brain are still maturing. The lungs are producing surfactant, a substance that prevents the air sacs from sticking together after birth. This development is crucial for your baby's breathing once they enter the world. The brain will continue to develop even after birth, with significant growth occurring until around age 2.
• Physical Features: At 39 weeks, your baby's skin is hardening and gaining a layer of fat to help regulate their body temperature. The nails may extend past the fingertips, and if you're having a boy, the testicles have likely fully descended into the scrotum. The protective vernix coating is mostly gone, except in areas like under the arms, in elbow creases, and under the chin.
• Weight of the Foetus: Your baby is approximately 35-36 cm in length and weighs around 3.3 kg. However, keep in mind that these are averages, and babies come in all shapes and sizes. Your healthcare provider will monitor your baby's growth and ensure they are on track.
• Movement of the Baby: Despite the cramped quarters, your baby will still be moving around, although the type of movement may change. Instead of sharp kicks, you might feel more rolling movements or your baby trying to stretch and get comfortable. They may have dropped lower into your pelvis, relieving some pressure on your uterus but increasing the pressure on your bladder.

Physiological Changes During Week 39 of Pregnancy

• Cervical Changes: At 39 weeks, your cervix is thinning (effacement) and may start to dilate. This process is a sign that your body is getting ready for labour. Your healthcare provider will monitor these changes during your regular check-ups.
• Braxton Hicks Contractions: You may experience more frequent and intense Braxton Hicks contractions, which are practice contractions that help prepare your uterus for labour. These contractions are usually irregular and don't progress in intensity or frequency like true labour contractions.
• Physical Discomfort: As your baby descends into the pelvis, you may feel increased pelvic pressure, backaches, and pubic pain. Finding a comfortable position to sleep or rest can be challenging. Try using pillows to support your bump and relieve pressure points.
• Hormonal Changes: Hormonal shifts can lead to mood swings, anxiety, and fatigue. It's normal to feel a mix of excitement and nervousness as your due date approaches. Practice relaxation techniques like deep breathing or prenatal yoga to help manage stress.

• Weekly Check-Ups
  
  You'll have regular doctor visits to check your baby's position, measure your fundal height, and assess your overall health.
   
• Group B Strep Screening
  
  Between 36-38 weeks, you'll be tested for group B streptococcus (GBS), a type of bacteria that can be harmful to your baby during delivery. If you test positive, you'll receive antibiotics during labour to prevent transmission to your baby.
   
• Cervical Checks
  
  Your doctor will perform pelvic exams to check for cervical dilation and effacement, which indicate progress towards labour.
   
• Fetal Monitoring
  
  Your healthcare provider will monitor your baby's heartbeat and movements to ensure their well-being. If there are any concerns, additional tests like a non-stress test or biophysical profile may be recommended.
