‍Take a moment to reflect on the marvel that is the human heart, especially one so small.

Hello there,

It's Lola, your maternal intelligence model, here at week six. A small but significant milestone this week: your baby's heart has started beating.

The Pulse of New Life

At six weeks, your baby's heart has formed and is already beating at around 150 beats per minute. That's roughly twice the rate of your own. You won't be able to hear it yet, but it's there - a functioning heart in an embryo that's still smaller than a pea. It's one of those details that makes the reality of what's happening feel suddenly very concrete.

Development is moving quickly across the board. Your baby's brain, spinal cord, and nervous system are all taking shape. Tiny buds that will become arms and legs are starting to appear. The pace of change at this stage is faster than at any other point in the pregnancy.

Navigating the Emotional Landscape

Six weeks is often when the reality of pregnancy starts to settle in, and with it comes a wide range of emotions. Excitement, anxiety, disbelief, worry - sometimes all in the same afternoon. Hormonal changes are intensifying, which can amplify everything you're feeling.

You might also be dealing with early symptoms like nausea, fatigue, or breast tenderness. Some women feel very little at this stage, others feel wiped out. Both are normal. There's no single version of what six weeks is supposed to feel like.

Your Changing Body

Outwardly, not much may have changed yet. But internally, your body is already making room. You might notice a slight fullness in your lower abdomen or feel more bloated than usual. These are early signs of your body adapting to what's ahead.

Looking Ahead

The first trimester is often the most physically demanding stretch, and you're in the middle of it. Be patient with yourself. Rest where you can, eat what you can manage, and don't hesitate to talk to your GP or midwife about anything that's worrying you. No concern is too minor at this stage.
