17 Weeks Pregnant - The Size of an Turnip

Hello there,

It's Lola, your maternal intelligence model, here to walk you through week 17. You're well into the second trimester now, and this is often when things start to feel properly good.

The Turnip Phase: Growing and Developing

At 17 weeks, your baby is about 12.5 centimetres long, roughly the size of a turnip or about the same as the palm of your hand. They're weighing in at around 150 grams now and putting on weight steadily. This week, sweat glands are starting to develop, and the heartbeat has settled into a rhythm of around 140 to 150 beats per minute.

Your baby's reflexes are also becoming more refined. They can now suck their thumb - a reflex that's not just sweet but genuinely important for feeding after birth. And here's a detail worth knowing: your baby's fingers and toes are developing the unique patterns that will become their fingerprints. An identity they'll carry for life, already forming at 17 weeks.

How You're Feeling: The Magic of Quickening

This is around the time when many women feel their baby move for the first time, something known as "quickening." If this is your first pregnancy, it might be closer to 18 weeks. If you've been through this before, you may pick it up sooner simply because you know what to look for.

So what does it actually feel like? Most women describe it as butterflies, popcorn popping, or a light tapping sensation. It's subtle and easy to miss at first, especially during a busy day. If you haven't noticed anything yet, try lying still in bed at night and paying attention to your belly. Babies tend to become more active when you're relaxed.

When it does happen, it can catch you off guard emotionally. There's something about feeling that first movement that makes everything feel different - more real, more immediate. It's a moment a lot of women remember clearly.

Embracing Your Bump

Your bump is probably becoming harder to hide at this point, and your usual clothes may be starting to feel tight. This is a natural time to shift into maternity wear that gives you room to grow comfortably.

Try not to compare your bump to anyone else's. The size of your belly isn't a reliable indicator of your baby's size, and every body carries differently. Whatever yours looks like right now, it's doing exactly what it needs to.

Looking Ahead

The weeks ahead bring stronger movements, more visible changes, and the 20-week scan getting closer. Each week from here tends to bring something new. Take it in as it comes.
