Still tiny. But growing quickly 💛

You may only have known about your pregnancy for a few days. Perhaps you've already started imagining the months ahead, or perhaps you're simply wondering why you're suddenly so tired. Meanwhile, your little one is very busy.

📌 Week 5 at a glance

• Trimester: First
• Baby's size: about the size of a sesame seed (around 2 mm)
• Still to come: roughly 35 weeks (a typical pregnancy lasts around 40 weeks)

🌱 Your little one this week

At 5 weeks, your baby is still an embryo, about the size of a sesame seed.

Even so, big things are underway. The embryo is settling into three layers of cells, and each layer will go on to become different parts of your baby: one will form the skin and nervous system, one the heart, blood and muscles, and one the digestive system and lungs.

The brain and spinal cord are also starting to form from a tiny structure called the neural tube. The heart is beginning to take shape too, and it will start to beat very soon.

🌷 And how about you, Mum?

Many mums first realise they're pregnant around this week. If that's you, congratulations, and take all the time you need to let it sink in.

Tiredness is one of the most common early feelings, and it can be surprisingly strong. You might also notice queasiness, tender breasts, a stronger sense of smell, or moods that swing from happy to teary and back again. Others feel almost nothing, which is just as normal. Your body is doing a lot of quiet work in the background, and every pregnancy feels different.

🍽️ Food for thought: vitamin C

Vitamin C is found in lots of colourful fruit and vegetables. It helps your body make collagen, a protein found in skin, bones and blood vessels, and it helps your body absorb iron from plant foods such as beans and leafy greens.

Everyday foods that contain vitamin C include:

• Guava (jambu batu) and papaya
• Oranges and other citrus fruit
• Capsicum (bell peppers)
• Strawberries and kiwi fruit

A simple idea: a few slices of papaya or guava alongside a meal. Nothing complicated needed. If you're curious about vitamins or supplements, your doctor, midwife or pharmacist can talk through what suits you.

✨ Little things that may feel nice

• Many mums find that a short rest or an earlier night helps when tiredness arrives
• A few simple snacks nearby can feel handy if your tummy is a little unsettled
• Some mums like to tell one trusted person first, so the news has a soft place to land
• A slow stroll or a gentle stretch can be a nice way to freshen up

🩺 Coming up

If you haven't already, this is a good moment to let a clinic know you're pregnant and ask about booking your first antenatal visit. In Malaysia, this can be at a Klinik Kesihatan or a private clinic of your choice. There's no need to feel rushed. It's simply a friendly first step, and the team can walk you through what happens next.

If you have an ongoing health condition, it can also be helpful to let your regular doctor know about your pregnancy early on.

👨👩👧 Partner's corner

Tiredness can arrive without warning, so a little extra help goes a long way. Taking over an evening chore or making a simple meal can mean a lot right now. And if the news still feels a bit unreal, that's completely normal too.

❓ Quick questions

Why am I so tired already?
Early pregnancy brings big changes behind the scenes, and tiredness is one of the most common early feelings. Many mums find it eases as the weeks go by, though every pregnancy is different.

Is it okay if I don't feel any symptoms?
Yes. Some mums feel very little in the early weeks, and that is completely normal.

💛 A little moment for the two of you

At five weeks, there may not be a bump. There may not be much for anyone else to see.

But inside, some of the earliest building blocks of your baby's body are taking shape. So if today you're tired and wondering why your body feels so different, remember that there's a lot happening in a very tiny space.

One week at a time, little one. 🦕
