Is it normal to feel little hiccups in my belly? 🤔

Yes — and it's adorable! Those rhythmic taps are likely your baby hiccuping. At week 24 it's a sign their little lungs are practicing. 💛

This week: baby is the size of an ear of corn 🌽

40 weeks, one friend the whole way

A new tip every single day

Written for exactly where you are — from the first flutter to the first hello.

Week 1

Fast food vs. the baby

Have you ever tried to play sports while on a diet of greasy fries and burgers? The experience probably wasn’t great. Pregnancy requires us to be even more physically fit than a regular exercise routine does.

Week 4

Microscopic and beloved

Most likely, you have only just made sure that you are pregnant after seeing two strips on the test. Okay, who are we kidding? Two strips on all 10 tests! Emotions are going wild in you, and in everyone you've managed to tell? Not surprising!

Week 6

Smile to mommy!

A miracle happens this week — your baby has a little face: eyes, nose, mouth, and ears which you will kiss many many times.

Week 9

Listen to your heart, baby

The little athlete is getting stronger: tiny muscles are being formed this week. But it will take at least another month or two before you can feel the baby’s kicks.

Week 11

Little scratchy hands

A new week has started and the baby changed again. How does she not get tired of the endless changes?!

Week 14

Are you a yeti?

Congratulations, the second trimester has begun! The baby is also very happy about this: she actively makes faces and smiles because her facial muscles are already sufficiently developed to do this.

Week 17

And who is overgrown with fat?

Your baby’s skeleton is becoming more dense and strong, and the umbilical cord — the main "thread" connecting the fetus with you — is getting thicker.

Week 19

Little piggy

The sensory development of your child is perfect! There are separate areas for smell, taste, hearing, sight, and touch all identified within the brain. So feel free to talk to the baby, sing songs and read fairy tales: be sure that she hears you!

Week 22

You are being watched!

This week your little secret agent is watching you. The brain of the baby has reached a decent size and already weighs 0.22 lbs. (100 grams), it is very well developed and therefore ceases to grow so quickly.

Week 24

Calm down, Mommy!

The baby has grown a little more and looks more human. She now has the sweetest face with eyelashes and eyebrows and you can already see the hair on her head. What color is her hair, who does she look like?

Week 27

Who is speaking?

Your child is still so small, and already hears not only your voice, but also the voices around you. True, everything she hears is muffled.

Week 30

Grow up and undress!

Every day the baby gets bigger and smarter. Now that she has fat cells that protect her from the cold, she throws off a light fluff (called lanugo, remember?) that has covered her body all this time.

Week 32

Do you need a mirror?

Well, your little human is almost perfect: all her main organs are fully developed, only the lungs, the pancreas, the pituitary gland and the adrenal glands continue to mature.

Week 35

Little egghead!

Now that there is less space left in the uterus, your baby’s movements are reminiscent of the movements of a large beetle. There is no magic number to tick off — what matters is her own pattern, and by now you are the world expert on it.

Week 37

Postpartum depression

It’s important to be aware of a condition that can occur after giving birth. Postpartum depression can happen to any new mother, but keep in mind that it only happens in 10–15% of cases. There is no need to fret, but you do need to know the symptoms.

Week 40

Go out, the time has come!

Finally! This is the official end of your pregnancy, although your baby doesn't seem to have gotten the memo. Now hold on and get ready! About 30% of babies are born at 40 weeks.

Development, week by week

See every stage in real 3D

Spin the model with your finger and read what's happening — the same cards you get in the app, a new stage every two weeks.

Great news, the baby looks more like a human! His ears and lips are being formed, on his hands and feet you can already notice the beginnings of fingers and toes.

Before you start

Questions people ask us

Is Hello Belly free?

Yes. Tracking, the AI companion, guided meditations and the week-by-week guides are free to use. Premium removes the one-tip-a-day pacing inside your current week and covers your partner on the same subscription, with a 3-day free trial.

What week of pregnancy am I in?

Pregnancy weeks are counted from the first day of your last menstrual period, not from conception, which is why you are usually counted as about 4 weeks pregnant when a test first turns positive. Enter your due date in Hello Belly and it works out your week, trimester and how many weeks are left.

Can I ask Hello Belly pregnancy questions at night?

That is what it is built for. Hello Belly is a chat-first companion that knows which week you are in and remembers what you told it earlier, so a 2am question gets a straight, judgment-free answer instead of a search-engine rabbit hole. It is educational support, not medical advice — anything urgent goes to your provider.

Does Hello Belly show baby development week by week?

Yes. Every stage of your baby's development is shown as a real 3D model you can spin with your finger, alongside the week's development notes, size comparison and what is changing in your body.

Can my partner follow the pregnancy too?

Yes. A family account brings your partner into the same pregnancy — they see the same weeks, tips and journal — and one Premium subscription covers you both.

Is my pregnancy data private?

Yes. Your chats and health entries are yours, never sold, and never used to advertise to you. Bump journal photos stay in your own iCloud private database — we store none of those bytes on our servers.

Meet your due date with a little more calm.

Use it right here in your browser, or get it on your phone.

Bring your partner along — family accounts share one subscription, so you both follow the same pregnancy.
