Third trimester

Week 40

due date

Eight short cards a week — the baby, your body, and you. You can read them in ten minutes and close the app.

Baby

What's growing

Average due date

Only about 4–5% of babies are born exactly on their estimated due date. 'Late' is usually just normal.

Body

What's changing in you

The longest project

Your body is finishing the longest single physiological project it has ever done. Eat, walk, rest, repeat.

Brain

Maternal brain

Time distorts

Days feel long, weeks feel short. This is normal end-of-pregnancy temporal experience, not anxiety.

Bond

You & baby

You are already a parent

Waiting is its own labor. The relationship has begun.

Partner

For your partner

Be the calm room

Lights low, snacks ready, phone charged. Co-regulation is the partner's first contribution to labor.

Movement

Move with care

Move when it helps

Walk, sway, rest. Postpartum return-to-exercise begins only when you, your provider and your pelvic-health physio agree — Davenport and colleagues at the Program for Pregnancy and Postpartum Health (University of Alberta) have led the recent evidence base for safe postpartum return.
