Pregnant in week 19
In week 19 your baby is the size of a large tomato. The skin is now covered by the protective vernix, and the brain develops the areas that control the senses. Round ligament pains at the sides of the belly are common.
Your baby in week 19
Your baby measures around 15 centimetres and weighs about 240 grams. The skin is still wrinkled, because the fat layers haven't filled out yet, but they are well on their way.
A greasy, whitish layer – vernix caseosa – now covers the skin and protects it from the constant bathing in amniotic fluid. On top lie the fine downy hairs, lanugo, which help the vernix stay in place.
In the brain the areas that will process sensory input – taste, smell, hearing, sight and touch – are developing. If you are expecting a girl, her egg follicles are already numerous, and in boys the testicles are descending.
Your body and symptoms in week 19
Many experience round ligament pains – short sharp pulls at the sides of the belly as the uterus stretches the ligaments that hold it in place. It is harmless and eases when you change position.
The bump grows rounder, and your navel may begin to flatten or pop out. Some get a dark line down the belly and darker pigmentation on the face (the pregnancy mask), which fades after birth.
Blood flow is high, so you may feel warm and get a stuffy nose. Appetite is often good, and a steady weight gain of half to one kilo a week is typical from now on.
Good advice for week 19
Change position for side pulls
Round ligament pains ease if you move calmly, change position and support the bump. Try leaning towards the pain instead of away from it.
Protect your skin from the sun
The pregnancy mask and dark spots are intensified by the sun. Use sunscreen and a hat if you are out a lot – the pigmentation fades after birth.
Drink plenty of water
Fluids keep your blood volume up, counteract constipation and headaches and help with the feeling of warmth many get now.
Enjoy the movements
The kicks become stronger and more frequent. Place a hand on your belly when you rest – your baby is often most active once you have settled down.

Frequently asked questions in week 19
What is the pregnancy mask?
It is darker patches on the face (melasma) caused by hormones and sun. It is completely harmless and usually fades on its own in the months after birth.
Can I find out the sex at week 19?
Yes. At the anomaly scan around weeks 19-20 the sex can often be seen if you wish. If you want to be certain, we offer a gender scan with a gender guarantee.
Are pulls and tightenings contractions?
Usually not. Round ligament pains and occasional tightenings are normal. Regular, increasing and painful contractions, however, should be assessed.
