  • The baby continues to grow and gain weight, but at a slower pace.
  • The placenta still functions but its capacity may decrease after week 42.
  • The amniotic fluid gradually decreases, which is closely monitored.
  • The baby's nails and hair may have grown quite long.
  • The vernix caseosa (the waxy coating) has largely dissolved and the skin may be wrinkled.
Your body

Physical changes

  • The body is ready for labor – the cervix may be partially open and soft.
  • The belly can feel enormous and heavy.
  • The hormones oxytocin and prostaglandin are working to initiate labor.

Common symptoms

  • Continued fatigue and sleep deprivation.
  • Intense practice contractions that can be difficult to distinguish from real labor.
  • Downward pressure and pain in the pelvis.
  • Frustration and impatience that the baby hasn't arrived yet.
  • Increased vaginal discharge.

Emotional changes

  • Frustration and impatience are completely normal – you are not alone in feeling this way.
  • Worry about being overdue and the baby's well-being.
  • Tired of well-meaning questions and comments from those around you.
  • Try to focus on the fact that each day brings you closer to meeting your baby.
Good to know
  • It is completely normal to go past your due date – about half of all first-time mothers give birth after the estimated date.
  • Your healthcare team will offer increased monitoring with CTG and possibly ultrasound to check amniotic fluid levels.
  • Induction is usually offered if the pregnancy continues beyond 41+0 to 42+0 weeks, depending on the region and individual assessment.
  • Induction can be done with a balloon catheter, prostaglandin gel, or an oxytocin drip – your midwife will explain what applies to you.
  • Try to keep busy with enjoyable activities while you wait.

Appointments & check-ups

  • Post-dates monitoring with CTG (fetal heart rate monitoring) and assessment of amniotic fluid levels.
  • Possible ultrasound to assess amniotic fluid and placental function.
  • A membrane sweep may be offered to try to start labor naturally.
  • Planning of induction if labor does not start spontaneously.

Important

  • Decreased fetal movements – contact the delivery ward immediately, regardless of the time of day.
  • Water breaking – note the color and time, contact the delivery ward immediately. Green or brown fluid requires urgent assessment.
  • Heavy bleeding – call emergency services.
  • Regular contractions – contact the delivery ward.
  • If you feel worried about the baby's movements or well-being – trust your instinct and contact your healthcare provider.
Food & nutrition

Good to eat

  • Continue eating nutritiously and regularly – the body needs energy for labor.
  • Energy-rich snacks: dates, nuts, fruit, energy bars.
  • Drink at least 2–2.5 liters of water per day – good hydration is especially important now.
  • Easily digestible meals such as soup, porridge, and sandwiches.

Be aware of

  • Have food and drinks ready to bring to the hospital.
  • Do not eat too heavily if you think labor may be near.
  • Maintain good eating habits – it gives you strength during labor.

Avoid

  • Unpasteurized products.
  • Raw fish and raw meat.
  • Alcohol.

Supplements

  • Continue with prescribed supplements.
  • Vitamin D.
  • Iron as needed.
Exercise

Gentle movement can help start labor and keep you in good shape. Do what feels good and avoid pushing yourself.

Going past your due date is a wait that can be mentally tough. Be kind to yourself, surround yourself with supportive people, and remember that it will be time soon. Each day brings you closer to your baby.

Suggested activities

  • Walks – a classic and proven way to encourage labor
  • Pelvic rocking and swaying on a Pilates ball
  • Relaxation and deep breathing
  • Light stretching and gentle movements

Avoid

  • Intense or strenuous exercise
  • Activities far from the hospital
  • Anything that causes pain or discomfort

Pelvic floor exercises

Continue with pelvic floor relaxation exercises. During labor, it is about releasing and opening – not holding back.
