Semaine 40 de grossesse
Contenu revu pour la dernière fois le 2026-08-10.
Une traduction française est en préparation. Les informations ci-dessous sont affichées en anglais pour le moment.
Votre bébé cette semaine
This is due date week! Your baby is approximately 20 inches long and weighs about 7.5 pounds on average, though healthy babies range widely from 6 to 9 pounds. Baby's skull bones can mold and overlap to navigate the birth canal — they'll round out in the days after birth. All organ systems are fully mature and ready for independent life. Baby continues to receive antibodies from you right up until delivery, building a starter immune system. The vernix coating has mostly been absorbed, though some may still be visible at birth, especially in skin creases.
Ce que vous pouvez ressentir
You are very uncomfortable — and that is completely understandable. The anticipation and physical strain of late pregnancy are intense. Your cervix is likely effacing and dilating. You may experience more intense Braxton Hicks contractions or prodromal labor (real contractions that start and stop). Emotional ups and downs are completely normal — excitement, fear, impatience, and joy may all cycle through in a single day. Some women experience a burst of energy right before labor begins, sometimes called the "final nesting urge."
Symptômes courants
- Your due date is here! Only about 5% of babies arrive exactly on their due date.
- You may notice a "bloody show" — pinkish mucus signaling the cervix is changing.
- Intense pelvic pressure and lower back pain may signal labor is approaching.
- Nesting urges, loose stools, and restlessness can occur in the final days.
Conseils de la semaine
If you pass your due date, don't worry — only about 5% of babies arrive exactly on their due date, and going to 41 weeks is common. Your doctor will discuss monitoring and induction options, typically recommending induction between 41 and 42 weeks. Continue monitoring fetal movements and attend all scheduled appointments. Try to rest, stay nourished, and keep your spirits up. When true labor begins, trust your preparation, your body, and your medical team. You've got this.
Bien manger
- Eat easily digestible, carb-rich meals for quick energy — pasta, toast, and fruit.
- Stay hydrated — sip water, coconut water, or electrolyte drinks throughout the day.
- Keep labor snacks handy: applesauce, crackers, honey sticks, and juice.
Point nutrition
- Continue your prenatal vitamin — you'll transition to a postnatal version after birth.
- Adequate iron stores now will help with postpartum recovery and blood loss.
Bien-être au quotidien
- Walk, bounce on a birth ball, and try nipple stimulation if approved by your provider.
- Rest as much as you can — conserving energy now pays off during labor.
- Know when to call: regular contractions, water breaking, bleeding, or reduced movement.
- Trust your body — you are prepared for this moment.
Pour votre partenaire
The big day is here or very close! When labor begins, be her advocate, her comfort, and her cheerleader. Hold her hand, offer ice chips, apply counter-pressure to her back during contractions, and remind her to breathe. Capture the moment but also be fully present — put the camera down when she needs you. After delivery, support skin-to-skin contact and the first feeding. Welcome to fatherhood — your life is about to change in the most beautiful way.
Signes à signaler à votre professionnel de santé
- No fetal movement for 2+ hours during baby's usual active time — seek immediate care.
- Heavy bright red bleeding — go to the hospital without delay.
- Severe headache with vision changes or upper abdominal pain — preeclampsia emergency.
- If you pass 41 weeks, your provider will discuss induction to reduce stillbirth risk.
