Pregnancy week 19: symptoms, baby size and tips

Pregnancy week 19 takes you almost to the halfway point of your pregnancy, and it’s a perfect time to enjoy the second trimester. Your baby is now the size of a mango, their skin is protected by the vernix caseosa and they’re noticing more and more of the world around them: your voice, your heartbeat, the sounds of your everyday life. Let me walk you through it, as always ❤️.

If you’re coming from pregnancy week 18, you’re on a great track. And to have the whole path at hand, check out our pregnancy week by week guide.

What is pregnancy week 19?

As always, pregnancy weeks are counted from the first day of your last period (LMP), not from conception. In week 19 you’re about 17 weeks from fertilisation, in your fifth month of pregnancy (weeks 18–21) and still right in the second trimester, which runs from week 13 to week 28.

You’re only about a week away from the halfway point of the pregnancy. For many women this is one of the most enjoyable stages: fewer symptoms, more energy and a bump that shows more every week. Your uterus is clearly above your navel and it’s normal to notice your waist getting wider and your body rounding out.

How is your baby developing in week 19?

Your baby is still growing fast, and this week brings some big news for their skin and their brain:

Their skin is covered in vernix caseosa: that whitish, creamy coating that wraps them and protects them from the amniotic fluid, like a natural lotion. It keeps them safe and stops their skin from wrinkling.
Lanugo now covers their whole body: that super-fine hair that runs across their body which, along with the vernix, keeps them protected and warm inside the sac.
Their brain is specialising the senses: it’s starting to set aside areas dedicated to smell, taste, hearing, sight and touch. One of the big developments this week.
Their kidneys are now producing urine: they make urine and pass it into the amniotic fluid, a process that helps keep that fluid balanced.
Their sweat glands are forming: their skin is getting ready for life outside the womb.
They keep practising movements: stretching, turning around and moving their arms and legs. Some mums feel their first kicks around now.

If you haven’t taken a test yet, don’t worry: your hCG is still high and any test is very reliable. You can take our free online pregnancy test for guidance with your symptoms, and if you fancy a distraction, try our finger pregnancy test game: it’s just a game, not a real test.

What symptoms are normal in week 19?

Every pregnancy is different, but in week 19 many women feel especially good. That said, there are some typical symptoms at this stage:

Movements you start to feel: flutters, bubbles or tickles in your lower belly. Some mums feel their baby move for the first time this week, especially if they’ve been pregnant before.
Linea nigra on your tummy: that vertical line down your belly is darkening because of hormones. Completely normal and it usually fades after birth.
Itchy skin: the skin on your tummy stretches as your bump grows and it can start to itch. Moisturisers help to relieve it.
The first stretch marks: the rapid stretching of your skin can leave pink or brown marks. Good hydration helps, although they’re also partly genetic.
Twinges or cramps in your lower belly: the round ligament keeps stretching as your uterus grows. That’s normal, but if the pain is strong or persistent, talk to your doctor.
Back pain: your bump grows and your centre of gravity shifts; lower-back discomfort is common. Gentle stretching and good posture help.
Leg cramps: especially at night. Gentle stretching and staying hydrated usually help.
Dizziness or feeling light-headed when you stand up: your blood volume rises and your blood pressure can drop. Stand up slowly.

Hardly any symptoms? Also completely normal. Every woman experiences each week in her own way.

How big is the baby in week 19?

Week 19 baby, the size of a mango

The baby in week 19 measures about 15 centimetres (from head to toe) and weighs around 200 to 240 grams, roughly the size of a mango. And even though they’re still small, they’re full of activity this week:

Their skin is covered in vernix and lanugo: they’re fully protected inside the amniotic fluid.
Their brain keeps growing: it’s setting aside specific areas for each sense (smell, taste, hearing, sight and touch).
They hear better every day: their tiny ear bones are maturing and they pick up your voice and your heartbeat.
They move, stretch and turn around: even though you may barely feel it yet.
Their kidneys are working: they already produce urine and pass it into the amniotic fluid.
Their sweat glands are forming: their skin is preparing for life outside the womb.

Fun fact: even though they move a lot, it’s very likely you still can’t feel their movements, especially if it’s your first pregnancy. First-time mums usually feel the first movements around week 20 or a little later. Don’t worry if you notice nothing yet: it’s completely normal.

Tips for week 19

Don’t chase feeling movements: if you still feel nothing, remember it’s normal, especially in a first pregnancy. Movements are usually felt between weeks 18 and 22.
Moisturise your skin: use a moisturiser on your tummy, breasts and thighs to relieve itching and help with elasticity. Also drink plenty of water.
Take care of your back: as your bump grows, try to sit and walk with a straight back and avoid lifting heavy things.
Sleep on your side, preferably the left: it improves circulation to the uterus and helps with heartburn. Put a pillow between your knees.
Stand up slowly: avoid sudden changes of posture to prevent dizziness, and stay hydrated.
Keep taking folic acid and eating well: fruit, vegetables, protein and hydration. Keep avoiding alcohol, smoking and raw foods.
Don’t self-medicate: always ask your doctor before taking anything, even creams or natural remedies.
Work out your due date with the gestogram and track your week with how many weeks pregnant am I.

FAQ

What month am I in during week 19?

You’re in your fifth month of pregnancy (weeks 18–21), within the second trimester. You’re about 17 weeks from fertilisation and nearly at the halfway point.

How big is the baby in week 19?

About 15 centimetres from head to toe and between 200 and 240 grams: roughly the size of a mango. Their skin is already covered in vernix caseosa and lanugo.

Why do I have a dark line on my tummy?

It’s the linea nigra, which darkens because of pregnancy hormones. It’s completely normal and it usually fades after birth.

Because your skin stretches as your uterus and bump grow. Moisturisers help to relieve the itching. If the itching is intense, widespread or worrying you, talk to your doctor.

Yes. Their tiny ear bones are maturing and they pick up mainly your voice, your heartbeat and soft sounds from outside.
