Hello! You have reached another important week in your beautiful pregnancy journey. You are now in your 19th week. By now, your belly has likely started to show, and you may even be feeling your baby growing inside. Perhaps you have even started to feel those tiny movements. It is such an exciting time, isn't it? Let’s take a look at the amazing things happening in your body and your little one's body during this 19th week.
Amazing Baby Development: What happens in the 19th week?
By this week, your baby is about the size of a small mango! Think about it... something you can hold in your hand. Your baby is about 15 cm long and may weigh around 240 grams. Of course, every baby is different, so there may be slight variations.
What is this white, cheese-like substance? – Let’s learn about ‘Vernix Caseosa’!
Have you heard the name 'Vernix Caseosa'? Your doctor might have mentioned it. This is one of the most special things happening in your baby's body this week. Simply put, it is a white, waxy, thick substance that covers the baby's skin. It looks just like cheese. Some people even call it the "cheese coating."
This 'Vernix Caseosa' provides vital protection for the baby's skin. It is much like applying lotion to our own skin.
Why is 'Vernix Caseosa' so important?
Think about it: the baby is in a sac filled with fluid (Amniotic Fluid). Just like our fingers wrinkle when we stay in the water for too long while bathing, what would happen if the baby's delicate skin were constantly exposed to that fluid? The skin could become dry, rough, or irritated.
- Protecting the skin: The 'Vernix Caseosa' coating helps prevent this. It acts as a protective barrier between the baby's skin and the surrounding fluid. As a result, the baby's skin does not dry out, get scratched, or become chapped.
- Ease during birth: Because of this coating, the baby has a slippery texture, which helps them pass through the birth canal during delivery.
- Protection after birth: Even after birth, the 'Vernix' may remain on the baby's skin for a few days. It provides protection against fungal and bacterial infections. It also helps the baby's body regulate its temperature.
What about premature babies?
Generally, this 'Vernix Caseosa' coating is often seen on premature babies because they are born before it has completely dissolved while in the womb. Don't be alarmed if you see it; it is perfectly natural. It will gradually fade away after a few days.
Other amazing changes in the baby
It’s not just the 'Vernix Caseosa'; many other things are developing in the baby this week.
- Fine hair (Lanugo): A very fine, thin layer of hair grows all over the baby's body. This is called 'Lanugo'. The 'Vernix Caseosa' helps stick to this 'Lanugo'. Most of this 'Lanugo' will shed as the baby nears birth.
- Can you feel those tiny movements?: By now, the baby is moving quite a bit. If you haven't felt it yet, you will likely start feeling it in a week or two. At first, it feels like a butterfly fluttering in your belly or bubbles popping. This is called 'Quickening'.
- Can they hear your voice?: The baby's ears are now well-developed. The baby is starting to hear your voice, your heartbeat, and sounds from the outside. So, this is a great time to talk to your baby and sing songs.
- Starting to taste: The tiny taste buds on the baby's tongue are also forming. The flavors of what you eat can reach the baby through the 'Amniotic Fluid'!
- Tiny kidneys at work: The baby's kidneys have started producing urine. This urine is what contributes to the 'Amniotic Fluid'. Don't worry; this is a perfectly natural process.
- Genitals: During an ultrasound scan this week, it may be possible to identify the baby's genitals. This means you might be able to find out if you are having a boy or a girl.
How are you doing this week?
It’s not just the baby; your body is also undergoing major changes this week.
- Belly growth: You will notice your belly is starting to protrude. The uterus has likely reached the level of your navel.
- Some new discomforts:
- Backache: As your belly grows, the weight on your back increases, which can lead to backaches. Use a small pillow for support when sitting in a chair. Place a pillow between your legs when sleeping.
- Round Ligament Pain: As the uterus grows, the ligaments supporting it stretch. This can cause sharp pain on the sides of your thighs or lower abdomen when you stand up suddenly, laugh, or cough. It usually subsides after a short while.
- Dizziness: Your blood pressure may drop slightly, which can sometimes cause dizziness. Stand up slowly instead of jumping up suddenly.
- Leg cramps: Some people experience leg swelling or painful leg cramps at night. Drink plenty of water throughout the day. Eat foods rich in potassium (bananas, avocados).
- Heartburn and Constipation: These are common during pregnancy. Instead of one large meal, eat smaller, frequent meals. Eat more fiber-rich foods, fruits, and vegetables.
- Skin changes: You may notice a dark line running down the center of your belly (Linea Nigra). You might also get dark spots on your face (Chloasma/Mask of Pregnancy). These are due to hormonal changes and will fade after the baby is born.
The important ‘Anomaly Scan’ this week
Usually, between 18 and 22 weeks, a special ultrasound scan is performed. This is called an 'Anomaly Scan' (some call it a 'Detailed Scan'). This scan checks in great detail whether every organ of the baby (heart, brain, kidneys, limbs) has formed and is developing correctly. It also checks the position of the placenta and the amount of 'Amniotic Fluid'. This is a very important test, so be sure to get it done on the day your doctor recommends.
Things you can do for your well-being this week
During this time, you need to take good care of yourself as well.
- Nutritious food: Eat a healthy, balanced diet. Include vegetables, fruits, leafy greens, nuts, dairy products, fish, and eggs in your meals. Take your iron and calcium tablets as prescribed by your doctor.
- Drink plenty of water: Try to drink at least 2-3 liters of water a day.
- Exercise: Engage in light exercise. Walking or swimming are good options. However, consult your doctor before starting any new exercise routine.
- Adequate sleep: Get plenty of rest. Try to sleep for at least 7-8 hours at night. It is also good to take short rests during the day.
- Mental well-being: Stay happy. If you feel burdened, talk to someone you trust. Share these experiences with your partner and family.
- Talk to your baby: Since the baby can hear your voice now, talk to them, sing songs, and gently stroke your belly. These activities strengthen the bonding between you and your baby.
Remember: If you experience abnormal vaginal bleeding, severe abdominal pain, continuous leaking of fluid, or symptoms like fever, consult your doctor immediately.
