Week 40+ of Pregnancy: Labor Induction and Post-Term. Survival Guide

World
Motherhood

You’ve reached the end of pregnancy! This is the week of birth, although only a small percentage of babies are born exactly on their due date. Don’t worry if your baby hasn’t arrived yet: they’re taking advantage of each day to gain a little more weight and strengthen their lungs.

Your body is in “full preparation” mode: the cervix softens, dilates, and the baby descends completely into the pelvis. At any moment, regular contractions will begin, marking the start of labor.

Symptoms

Regular and painful contractions: If they occur every 5 minutes and last 1 minute, it could be time!
Loss of the mucus plug or discharge with a little blood.
Strong pelvic pressure or cramping pain.
Lower back pain and a feeling of “heaviness” in the abdomen.
Extreme fatigue or, conversely, sudden energy (nesting instinct).
Difficulty sleeping and anxiety about labor.
Baby’s movement slightly slower but constant.

Baby’s size

Your baby measures approximately 50–52 cm and weighs around 3.4–3.6 kg, like a medium watermelon!
Their body is completely formed and ready to be born:
Their lungs and brain are fully functional.
Their skin is smooth and soft.
They’ve lost most of the vernix (that whitish coating that protected them).
They can cry, open their eyes, and recognize your voice and scent from the first moment.

What to Do

Have your hospital bag, stem cell collection kit, and documents ready.
Stay alert for signs of labor: regular contractions, water breaking, or bleeding.
Inform your doctor if more than 40 weeks have passed without signs of labor; they may recommend induction.
Stay calm and breathe deeply.
Ensure you have the support of your partner or companion for when labor begins.
Sleep and rest as much as possible before the big moment.

Nutrition in Week 40 of Pregnancy

Eat small, light portions to avoid feeling heavy.
Prefer foods rich in natural energy, such as fruits, yogurt, nuts, and whole grains.
Stay well hydrated.
Avoid greasy or heavily seasoned foods.
If you have nausea, choose mild foods such as soups, whole grain bread, or compotes.
Avoid excess sugar and caffeine.

Tip: Have a small healthy snack ready to take to the hospital (for example, whole grain crackers or a banana).

Exercise in Week 40 of Pregnancy

At this stage, gentle movement can help stimulate the onset of labor and maintain calm.

Recommended exercises:

Short walks: help the baby descend and the cervix dilate.
Pelvic movements on a ball: relieve pressure and favor the baby’s position.
Deep breathing: prepares you to control contractions.

Benefits:
– Facilitates the onset of labor.
– Reduces anxiety.
– Relieves discomfort in the back and pelvis.
– Keeps you active and with better oxygenation.

Things You Should NOT Do:

Do not go far from home or the hospital.
Avoid long trips or physical exertion.
Do not self-medicate under any circumstances.
Do not stress if labor hasn’t started yet: each body has its own rhythm.
Avoid foods that may cause discomfort or bloating.
Do not ignore a decrease in the baby’s movements: if this occurs, see your doctor.

Frequently Asked Questions

What happens if I reach week 40 and have no signs of labor?

It is completely normal. Labor can occur between weeks 37 and 42. If the baby has not been born, the doctor will evaluate induction.

How do I know if my water broke?

You will feel a sudden or constant loss of clear fluid. If this occurs, go to the hospital immediately, even without contractions.

Is it normal to feel irregular contractions for days?

Yes, it is the body practicing for labor. But if they become rhythmic and more intense, it could be the real onset.

When should I go to the hospital?

When contractions are every 5 minutes for at least 1 hour, if there is bleeding or water breaking.

Can I eat before labor?

It depends on your doctor and the type of delivery planned. In some cases, avoiding solid foods is recommended.

What do I do if I'm afraid of labor?

Talk to your doctor, partner, or doula. Breathing and emotional support are key. Your body is prepared for this.

Will my baby move less?

Yes, they may move less because they have little space, but you should continue to feel them several times a day.

Can I induce labor naturally?

Walking, relaxing, or having sexual intercourse (if your doctor allows it) may stimulate it, but never use home remedies without supervision.

What happens if I need a cesarean section?

It is a safe option if natural delivery is not possible. The important thing is that you and your baby are well.

How should I prepare mentally?

Trust your body, breathe deeply, and surround yourself with calm. Soon you will meet your baby, and everything will have been worth it.
