What to Expect at 36 Weeks of Pregnancy: Preparing for Labor and Self-Care

Highlights

• Marks the ninth month of pregnancy, approximately 8.5 months from the last menstrual period.
• Baby weighs around 2.75 kg and measures 46 cm, with fully formed organs.
• Maternal symptoms include fatigue, back pain, leg swelling, frequent urination, and sleep difficulties.
• Signs of impending labor appear: Braxton Hicks contractions, mucus plug discharge, and occasional abdominal pressure.
• Preterm birth at this stage is generally manageable, with infants typically breathing independently.
• Important: monitor fetal movements, maternal health, nutrition, and physical activity.

Maternal Sensations at 36 Weeks

• At this stage, the baby is active, with at least 10 movements in a 12-hour period.
• Anxiety and emotional fluctuations are common: nervousness, irritability, tearfulness, fatigue, and drowsiness.
• Physical discomfort is frequent due to:
  • Heavily enlarged abdomen
  • Difficulty walking
  • Restricted movement
  • Enlarged breasts
• Braxton Hicks contractions may be felt as intermittent abdominal tightening, signaling the approach of labor.
• Positive sensations include increased energy, sometimes due to the baby dropping into the pelvis, especially in first-time pregnancies.

Abdominal Changes and Fetal Movements

• The baby moves lower into the pelvis, preparing for birth.
• This movement may relieve pressure on the diaphragm, easing breathing, but increases urinary frequency.
• Discomforts such as heartburn, nausea, and shortness of breath may decrease slightly.
• Fetal movements may appear less vigorous due to limited space, but remain noticeable.

Fetal Development at 36 Weeks

• Weight: ~2750 g
• Length: ~46 cm
• Cheeks are rounded, and the baby practices sucking reflexes.
• Skin is smoother due to decreased vernix; amniotic fluid volume slightly decreases.
• Hair, eyebrows, and eyelashes are visible; nail tips extend beyond fingers and toes.
• The baby responds to familiar voices, with heart rate ~140 bpm.
• Cranial bones remain soft and flexible to ease passage through the birth canal.
• Internal organs and systems are fully formed, and the baby is considered full-term for survival outside the womb.
• Genital development is complete.

Common Discomforts and Pain

• Back pain from increased weight and joint stress.
• Abdominal pressure due to internal organ compression.
• Ligament and pelvic pain from uterine support strain.
• Leg cramps and fatigue are common.
• Digestive issues like constipation or minor nausea may persist.
• Mild menstrual-like cramps are normal; stronger pain may indicate low amniotic fluid or preterm labor.

Signs of Labor and Preterm Birth

• Preterm labor at 36 weeks requires attention but is generally safe for the baby.
• Indicators of approaching labor:
  • Regular contractions
  • Mucus plug discharge
  • Rupture of membranes
• Braxton Hicks contractions are irregular and shorter in duration; true labor contractions are consistent and may be accompanied by bleeding.

Vaginal Discharge

• Normal discharge is viscous and may become pinkish near labor.
• Curd-like, purulent, or bloody discharge signals potential infection or placental issues and requires immediate medical attention.

Nutrition and Physical Activity

• Focus on plant-based foods, moderate dairy, and fresh juices rich in vitamins.
• Limit fluid intake to ~0.8 L per day; avoid alcohol and excessive sugar.
• Light exercise and daily walks improve circulation, reduce swelling, and maintain maternal health.
• Avoid strenuous activity, heavy lifting, and stimulants that may trigger contractions.

Recommended Tests and Examinations

• Ultrasound: to check placental maturity and fetal positioning.
• Blood tests: for infections (HIV, STIs) and biochemical markers.
• Vaginal swab: to assess microbial flora.
• Urine analysis: kidney function and preeclampsia monitoring.
• Doppler ultrasound: fetal oxygen and nutrient supply.
• CTG (cardiotocography): fetal well-being and oxygenation.

Tips for Expectant Mothers

• Remain calm and informed; panic increases stress and may worsen discomfort.
• Track fetal movements and report significant changes to your doctor.
• Prepare your hospital bag and documents in advance.
• Spend time outdoors and rest as needed.
• Follow your doctor’s guidance for nutrition, activity, and monitoring.
• Minimize infection risks and avoid unnecessary stress.
