19th week of pregnancy

The highlight of this week is undoubtedly the next prenatal check-up. The second ultrasound is coming up, and you're surely excited to see your baby – after all, quite some time has passed since the last ultrasound, and a lot has happened with your baby since then. Here you'll learn what happens during the examination and what else is important in the 19th week of pregnancy.

How big is your baby in the 19th week of pregnancy?

Your baby is about 15 centimeters long this week, comparable to a grapefruit. So far, your baby has been measured from crown to rump (crown-rump length, CRL). However, from the 19th week of pregnancy onwards, it is customary to use the so-called crown-heel length (CHL). From crown to heel, your baby is currently approximately 24 centimeters.

Week 19 of pregnancy: What's changing for you

You're probably already eagerly waiting to feel your baby for the first time. Maybe this week will be the moment when you notice the first kicks and movements of your baby. But even if you haven't felt anything yet, that's completely normal, because every body is different and especially for women expecting their first child, it can still take a few weeks.

You might now notice mild cramps. As long as the contractions occur no more than three times per hour and last no longer than 45 seconds, they are probably . This "exercises" your body and prepares it for birth. Your baby won't notice much of this, so you don't need to worry. However, if the practice contractions occur more frequently or are very intense, consult your midwife or doctor for advice to be safe.

The hormone progesterone ensures that your digestive tract relaxes and slows down, so that more nutrients can be filtered out of the food for your baby. As a result, many expectant mothers suffer from digestive issues such as constipation, which can now be further aggravated by the growing uterus. Constipation is not only uncomfortable, but it can also promote hemorrhoids. You can learn how to stimulate your digestion now in the article “ “.

Preventive examination and the second ultrasound

Between weeks 19 and 22 of pregnancy, the next with the second ultrasound takes place. During this visit, you will not only get a glimpse of your baby, but your doctor will also check whether all its organs are properly developed and examine the position and structure of your placenta. Additionally, the amniotic fluid level will be measured and your baby's size assessed. For more information on how ultrasound examinations are conducted and what exactly is examined, our Lillydoo gynecologist Christian explains in the video .

19th week of pregnancy: Development of your baby

By now, your baby's entire body is covered with lanugo hair and the protective vernix caseosa. This week, the head hair also begins to grow, which it will carry at birth. The fat layer of your baby is increasing, making its skin less and less translucent. Around the 19th week of pregnancy, the reproductive organs start to function: in girls, the vagina, uterus, and fallopian tubes are fully developed, and there are already eggs in the ovaries. In boys, the testes are now beginning to produce testosterone.

The organs are constantly developing, currently especially the area in the brain responsible for sensory perception, and your baby's senses are becoming more refined. Its sense of touch, for example, is already so well developed that it is aware of the boundaries in the womb: when it touches the uterine wall with its hands or feet, it instinctively pulls away. The heart is fully developed at this week, but its two chambers and two atria are not yet separated. Only after birth, when your child breathes independently, will its septa in the heart fully close.

In the 19th week of pregnancy, your child's dental ridge is also forming, although it will still take quite a while before the first little teeth appear.
