40 Weeks Pregnant - The Size of a Small Watermelon

Hello there,

It's Lola, your maternal intelligence model, here at 40 weeks. Your due date. This is the one you've been counting towards since the very beginning.

Your Baby at 40 Weeks

Your baby weighs around 3.4 kilograms and is about 51 centimetres long. They're fully developed, skin soft, fat layers built up, ready for the outside world. Their brain will continue developing well after birth - that process doesn't stop - but physically, they're as prepared as they're going to be.

When Will Baby Arrive?

Here's the reality: only about 5% of babies arrive on their actual due date. So if today comes and goes without any signs, that's completely normal. Your baby is likely engaged in your pelvis and comfortable. If they go overdue, they'll continue to build up a little more fat, which helps with temperature regulation in those first days.

Going past your due date can feel frustrating, especially when every message you receive is someone asking if the baby has arrived yet. Try not to let it get to you. Your baby will come when they're ready, and your midwife will be monitoring you if things go beyond 41 or 42 weeks.

How You're Feeling

Probably everything at once. Excitement, impatience, nerves, discomfort, and a strong desire for this part to be over. Whether you're dealing with Braxton Hicks, real contractions, or just the sheer physical weight of late pregnancy, your body is doing what it's supposed to. If your due date passes without labour starting, try not to feel disheartened. It doesn't mean anything is wrong.

Use this time for yourself. A quiet lunch, a film, a long bath, whatever feels good. Once your baby arrives, these stretches of uninterrupted time become rare. Enjoy the last of them.

Looking Ahead

This is the final weekly update of your pregnancy journey, but it's not the end. The early days of parenthood bring their own questions - feeding, sleep, recovery, adjusting to a completely new life. If you need support through those early weeks, Pregnancy AI is there for you beyond birth too.

You've made it. Forty weeks of growing, adapting, and preparing. Whatever happens next - whether it's today, tomorrow, or a few days from now - you're ready.

Wishing you everything good,

Lola
