- Liver: Large — gives baby that round tummy shape
- Skin: Pale and smooth (less wrinkled)
- Fontanelles: Soft spots on the head (close during the first year of life)
- Tear ducts: Not fully developed — newborns cry without tears at first

Your Body
Weight Gain
- Recommended total weight gain: 11–16 kg
- Distribution:
- Baby: 3–3.5 kg
- Placenta: 0.7 kg
- Amniotic fluid: 0.8 kg
- Uterus: 1 kg
- Breasts: 0.4 kg
- Blood volume: 1.5 kg
- Fat and fluid reserves: 3–4 kg
Baby Has Dropped
- For many, baby has now dropped deep into the pelvis
- Head is "engaged" and ready for birth
- Easier to breathe, but more pressure on the pelvis
- More frequent urination
The Cervix
- Softening (effacement)
- May start to dilate
- The process varies enormously from person to person
- Some are "ready" for weeks, others not until labor starts
Emotions at Your Due Date
- Excitement and impatience
- Frustration if nothing is happening
- Anxiety about birth
- Mood swings (hormones!)
- All these feelings are NORMAL
Signs That Labor Is Starting
Main Signs — Go to the Hospital!
Real contractions:
- Coming regularly (every 5–6 minutes)
- Lasting 60–90 seconds each
- Getting stronger and more frequent over time
- Continuing regardless of activity
- Often starting in the back, spreading forward
- Hard to talk through a contraction
Waters breaking:
- Can be a gush or a trickle
- Clear, pink, or greenish
- Smells sweet (not like urine)
- IMPORTANT: Call the hospital IMMEDIATELY, even without contractions
- Risk of infection increases after waters break
Intense pelvic pressure:
- Feeling of pressure and urge to push
- Baby is moving down into the birth canal
Other Signs (Can Come Days Before)
- Mucus plug / show
- Bloody show
- Diarrhea (body clearing out)
- Extreme tiredness
- Nesting instinct (urge to tidy and prepare)
- Increased irritability
When to Go to the Hospital?
General Guidelines
Contractions:
- Every 5–6 minutes or more
- Lasting 60 seconds or longer
- This pattern has continued for 1 hour
- Use a contraction timer app to keep track
Waters break:
- Immediately!
Heavy bleeding:
- More than a few teaspoons
- Immediately!
Other alarm signs:
- Significant reduction in fetal movements
- Severe pain that doesn't ease
- Severe headache + visual disturbances + swelling
- Chest pain or breathing difficulties
- Dizziness or fainting
Special Considerations
First-time parents:
- Can often wait a bit longer at home
- Labor usually takes longer
Those who've given birth before:
- Go earlier — labor can be faster!
Long distance:
- Go earlier if more than 90 minutes to hospital
If Baby Hasn't Come Yet...
What Is Normal?
Only 5% give birth on their due date. Most give birth:
- Week 38–42: Normal
- Week 41–42: "Past due"
- Past week 42: "Post-term"
Risks of Going Past Your Due Date
For baby:
- The risk of stillbirth increases gradually after the due date, but is still very low
- The overall stillbirth rate is low for babies born at term (week 37+)
- Risk increases somewhat after week 41, which is why a wellbeing check is offered
- Meconium aspiration (baby inhaling its first bowel movement)
- Low amniotic fluid
- Baby stops growing
- Large baby (difficult birth)
- Low blood sugar in baby
For the birthing parent:
- Longer labor
- Higher chance of assisted birth (forceps or ventouse)
- Higher chance of cesarean section
- Postpartum hemorrhage
IMPORTANT: Most people who go past their due date give birth to healthy babies!
Follow-Up When Past Your Due Date
Around week 41:
- Wellbeing check at hospital
- Ultrasound (baby's size, fluid levels)
- CTG (fetal heart rate monitoring)
- Vaginal examination (cervical ripening assessment)
- Discussion about the next steps
Monitoring may include:
- Counting baby's movements daily
- CTG monitoring regularly
- Ultrasound of amniotic fluid
Induction of Labor
When Is Induction Recommended?
Research (including the INDEX and SWEPIS studies, 2019) shows:
- Induction at week 41 can reduce risk compared to waiting until week 42
- Same cesarean rate as expectant management
- Fewer poor outcomes for baby
In most countries:
- Individual assessment
- Discussed at the wellbeing check around week 41
- Often recommended by week 42 at the latest
Bishop score (cervical readiness assessment): Assessment of how ready the cervix is for birth:
- 8+ points: Induction will likely succeed
- 6–7 points: Could go either way
- 5 or below: Induction may not succeed
If the cervix is not ready:
Cervical ripening methods:
- Prostaglandin: Medication that softens the cervix
- Foley balloon catheter: Mechanical stretch of the cervix
- Membrane sweep: Midwife separates the membranes
After ripening:
- Oxytocin drip (Pitocin/Syntocinon)
- Starts and strengthens contractions
Managing the Emotions at Your Due Date
If Nothing Is Happening
- Disappointment: Normal!
- Impatience: Understandable!
- Worry: Talk to your midwife
Tips for Handling the Wait
- Know your body is working — even if you can't feel it
- Avoid "due date police" — it's okay to ask people to stop asking
- Keep yourself occupied — hobbies, films, walks
- Rest — you'll need energy soon!
- Spend time with your partner — soon everything changes
- Talk about your feelings — it helps!
Don't Try to "Force" Labor
There are many folk remedies said to start labor:
- Pineapple juice
- Sex
- Long walks
- Spicy food
- Castor oil
- Raspberry leaf tea
There is no reliable scientific evidence that any of these effectively start labor. Baby comes when baby is ready. The only sensible things you can do are stay active with daily walks, train your pelvic floor, and rest well between them.
Final Check — Do You Have Everything Ready?
Hospital Bag
Double-check your hospital bag is fully packed and easily accessible. Your partner should know exactly where it is.
Car Seat
The car seat must be installed and tested. You'll need it for the ride home.
Contraction Timer
Download a contraction timer app or add it as a shortcut on your phone. It's invaluable when contractions start — it helps you record duration and intervals so you know when it's time to go to the hospital.
You Are Incredible!
You have been pregnant for 40 weeks (280 days!). Your body has:
- Created a whole human being from scratch
- Built a placenta
- Produced all the amniotic fluid
- Expanded blood volume by 50%
- Grown the uterus from the size of an egg to the size of a watermelon
- Prepared the breasts to produce milk
Tips for Week 40
- Use a contraction timer app with any contraction — it helps distinguish practice contractions from real ones
- Double-check your hospital bag one last time
- Stay active with daily walks — it can help baby descend
- Train your pelvic floor — it's never too late to strengthen it
- Rest and save energy — you'll need it soon!
- Silence your phone if needed — it's perfectly fine to avoid "has baby arrived yet?" messages
- Enjoy the final days as a pregnant person — take bump photos and write a diary
- Keep an eye on fetal movements — contact the hospital if you notice changes
For Your Partner
- Be patient and supportive — the wait can be frustrating for the pregnant person. Avoid asking "has anything happened?" every quarter hour
- Keep your phone on and be available at all times — cook, tidy, and keep the home ready
- Prepare mentally for your role during labor — read about breathing exercises, massage, and support techniques you can use
- Familiarize yourself with a contraction timer app so you can help time them when it starts
- Make sure the car has fuel and the route to the hospital is planned
- Pack a small bag for yourself: snacks, charger, change of clothes, book or music
Did You Know...?
- Only 5% of all babies are born on their due date. Most are born between week 38 and 42, and the average first-time parent actually gives birth 5 days after their due date
- Your body has expanded its blood volume by a full 50% during pregnancy — from about 5 liters to 7.5 liters. After birth, this gradually normalizes over the course of a few weeks
- Baby has been surrounded by up to about 1 liter of amniotic fluid at its peak, and has drunk and urinated hundreds of liters throughout the pregnancy — an impressive workout for the kidneys
- Newborn babies cry without tears in the first weeks. The tear ducts are not fully developed at birth and mature during the first weeks of life
Common Questions About Week 40
What happens if I go past my due date?
It's completely normal to go a few days past your due date. You'll likely be asked to come in for a wellbeing check around week 41, where they do an ultrasound, CTG (fetal heart rate monitoring), and vaginal examination. Together with your midwife and doctor, you'll assess whether induction is needed or whether it's safe to wait a little longer.
What is induction, and does it hurt?
Induction can be done in several ways — prostaglandin (medication that softens the cervix), a balloon catheter (mechanical stretch), a membrane sweep, or an oxytocin drip. The experience varies from person to person. Some find contractions come faster and more intensely than in spontaneous labor, while others notice little difference. Pain relief is available regardless of how labor starts.
Is it dangerous to go past your due date?
Most people who go past their due date give birth to healthy babies, but the risk of complications increases gradually after week 41. That's why healthcare teams monitor more closely after the due date, with more frequent check-ups and monitoring. Induction is usually recommended by week 42 at the latest.
What should I do while waiting?
Try to keep yourself occupied with things you enjoy — go for walks, watch films, read books, and enjoy the final moments of pregnancy. Rest well and save energy. Feel free to ask family and friends to avoid "has baby arrived yet?" messages. It's absolutely fine to put your phone on silent and take it easy.
What if I want to try natural methods to start labor?
There's no reliable evidence that any natural methods reliably trigger labor. Baby comes when ready. The best thing you can do is stay gently active, eat well, rest, and keep in touch with your midwife about how you're feeling. If you have concerns about going past your due date, discuss them with your care team.
Good luck with the birth, whenever it comes! You're going to do brilliantly!
