Something tiny has begun 💛

Maybe you've just seen two lines on a test. Maybe you're still looking at it, wondering if this is really happening. Or maybe you only have a feeling that something is different.

However you got here, welcome. Right now, nothing may look different on the outside — but on the inside, a very small and very important story has started. This is the first chapter of your Dino Bump journey, and we're so glad you're here.

📌 Week 4 at a glance

• Trimester: First
• Baby's size: about the size of a poppy seed (around 2 mm)
• Still to come: roughly 36 weeks (a typical pregnancy lasts around 40 weeks)

🌱 Your little one this week

At 4 weeks, your baby is called an embryo and is about 2 mm long — roughly the size of a poppy seed.

It has just settled into the lining of your womb, and it's already busy. A fluid-filled bubble called the amniotic sac is forming around the embryo to cushion it, and a tiny yolk sac helps provide nourishment in these very early days. Some of the outer cells will go on to form the placenta, the special organ that will later carry oxygen and nutrients from you to your baby.

Your body has also started making a hormone called hCG. It's the hormone that pregnancy tests look for, which is why a test can show two lines around now.

🗓️ “4 weeks”? But it only just began!

This one surprises almost everyone. Pregnancy weeks are counted from the first day of your last period, not from the day your baby began to grow. So at “4 weeks”, your baby has really only been developing for around two weeks.

It's why the numbers can feel a little confusing at first. Nothing is behind or ahead — it's simply how everyone counts.

🌷 And how about you, Mum?

You might feel quite different already, or completely like yourself. Both are very common.

Some mums notice a missed period, tender breasts, tiredness, queasiness, a metallic taste in the mouth, a stronger sense of smell, needing to pee more often, or mild period-like cramps. Others don't notice anything at all yet, and that's perfectly okay too. Early pregnancy looks different for everyone.

You probably don't look pregnant yet, either. With a first pregnancy, a visible bump often takes a while to appear.

🍽️ Food for thought: folate

You may have already heard about folate in early pregnancy. Folate is a B vitamin (vitamin B9) that's found naturally in food, while folic acid is the form used in supplements. Folate contributes to the growth of tissue during pregnancy, which is one reason it gets so much attention in the early weeks.

Everyday foods that contain folate include:

• Leafy greens such as spinach (bayam) and broccoli
• Beans, peas and lentils
• Oranges and other citrus fruit
• Eggs

You don't need to change everything overnight. If you're curious about supplements, including folic acid, your doctor, midwife or pharmacist can talk through what suits you.

✨ Little things that may feel nice

• Many mums find that resting when the body asks for it helps, as early tiredness is very common
• A water bottle within reach makes it easy to sip through the day
• Small, simple meals can feel gentler if your tummy is a little unsettled
• A slow, easy walk can be a nice way to enjoy some fresh air, if you feel up to it

🩺 Coming up

There's no rush to have everything figured out this week. When you feel ready, many mums book a first antenatal visit in the early weeks. A doctor or clinic can confirm the pregnancy, talk you through what to expect and answer your questions. In Malaysia, this can be at a Klinik Kesihatan or a private clinic of your choice.

A little tip: keep a note on your phone for questions as they pop up. By the time of your visit, you'll have a nice list ready.

👨👩👧 Partner's corner

If you're the partner reading this, you might feel excited, nervous, or a bit of both. That's all completely normal. At this stage, small things go a long way: a little help around the house, a snack on the way home, or simply listening. This is a journey you're on together.

❓ Quick questions

Is it normal to feel nothing yet?
Yes. Many mums don't notice much at this stage, and that's perfectly fine.

When can I take a pregnancy test?
Many home tests can show a result from around the time of a missed period. The instructions on the pack are the best guide for your particular test.

💛 A little moment for the two of you

You don't need to feel like a mum right away. You don't need a plan, a name or a nursery colour yet. Maybe you're excited. Maybe you're a little nervous. Maybe both at the same time.

For today, it's enough to know that something the size of a poppy seed has begun to grow, and that you've already started taking care of it just by being you.

Hello, little one. We have a long way to go together. 🦕
