10 Weeks Pregnant: Ten Fingers, Ten Toes, and Fingerprints All Their Own

Last week, your baby got a new name and a hidden set of teeth. This week, look at the hands.

By the end of week ten, your baby's fingers and toes are fully formed and separated, the last of the webbing gone, with the very first hint of tiny nails. And on the tips of those brand new fingers, something is beginning that no other person on earth will ever share. Let me show you.

Ten fingers, ten toes, and the first tiny nails

Remember those little paddles from a couple of weeks ago, the hands and feet with the fingers still webbed together?

They are finished now. Ten separate fingers. Ten separate toes. Longer, and free, and unmistakably hands and feet. The very beginnings of nails are appearing at the tips. And your baby can already bend at the elbows and wrists and curl those new fingers into a tiny fist.

The hand that will one day wrap around your finger and refuse to let go, that will reach up to be lifted, that you will hold crossing every road for years, is right now opening and closing for the very first time, in the dark, just practising.

The fingerprints that will be theirs alone

Now here is the part that stops me every single time.

On the tips of those new fingers, the skin has quietly begun a slow and secret work. Over these coming weeks it will buckle and rise into a pattern of tiny ridges, loops and whorls and arches, that is being drawn this very month for the first time.

That pattern has never existed before in the whole history of the world. And it will never, in all the billions of people still to come, be exactly repeated. It is your baby's fingerprint. Already beginning. Utterly, permanently, only theirs. The same prints they will one day leave on a fogged-up window, on a school worksheet, on your hand. Being sketched right now, on fingertips no bigger than the head of a pin.

A tiny body that actually works now

Your baby is not just shaped like a person this week. Parts of your baby have actually started working.

The kidneys are beginning to switch on. Over these weeks your baby starts swallowing tiny sips of the surrounding fluid and, yes, weeing it neatly back out again, a small plumbing loop running quietly all day long. The liver, the brain, the beginnings of so many organs are humming away, rehearsing the jobs they will do for a lifetime. None of it is finished. All of it has begun.

The head is still grand and round and about half of your baby, because that brain simply refuses to slow down. But the body is finally starting to catch up.

How big is my baby at 10 weeks?

Around three to four centimetres now, head to bottom, and just a few grams in weight. Small enough to still tuck completely out of sight. Big enough to have fingers, the start of fingernails, a working set of kidneys, and a fingerprint all their own.

Quite a fortnight's work, for someone barely the length of your thumb.

When will the sickness ease? Is the first trimester nearly over?

You are closer than you might feel.

Week ten sits near the top of that long first-trimester climb. For many women, the relentless nausea and the bone-deep tiredness begin to lift over the next couple of weeks, often somewhere around twelve to fourteen weeks, as the placenta takes over the great hormonal heavy lifting. It does not happen on a fixed day, and it does not arrive for everyone at once, so please do not measure yourself against anyone else. But for a great many women, real relief is now in sight.

There is a quiet reassurance in this stretch too. The enormous, delicate work of building all the major structures is largely behind your baby now, and the risk of miscarriage drops considerably as you reach the end of the first trimester. None of that erases worry entirely, I know. But it is real, and it is worth holding onto.

From Courtney. By week ten, I always felt like I was standing at a door I could not quite open yet. So close to the end of the first trimester, so ready to feel like myself again, and yet, on some days, far too queasy and too tired to believe it would ever come. If that is you, I promise you the door does open. For most of us, the weeks just ahead are when the fog begins to thin and a little energy creeps quietly back. And there is something tender about this particular week, knowing that inside you, right now, there are ten tiny fingers already being printed with a pattern that will be your child's signature for the whole of their life. You cannot see them yet. But they are there, and they are already entirely, only theirs. Nearly through, mama. Nearly through.

The one thing to do this week

Keep your folate going, or begin it now if you are only just starting. No guilt, ever, either way.

This is also a good week to look ahead to your first proper scan, the one many women have around twelve to thirteen weeks, if you have not already got it booked. It is worth jotting down any questions as they come to you, because they have a way of vanishing the moment you are actually in the room. And if the evening prenatal trick from last week is helping you keep things down, keep it going.

Coming up in week eleven

Next week, your baby starts to explore. Those new hands open and close, the mouth opens and closes, and your baby begins to wriggle and shift in earnest, though it is still far too soon for you to feel any of it. The bones are beginning to harden, the body keeps stretching longer, and that big head slowly, slowly starts to look a little more in proportion.

Week eleven is the home straight of the first trimester. I will see you there.
