19 Weeks Pregnant

Length of baby: 15cm (150mm)
Weight of baby: 240g (0.24kg)
At week 19, your baby is developing the five senses – smell, taste, touch, sound and sight – for use when out of the womb.


If you think your belly is huge now, well, sorry but you’ve got another think coming. Truth is, from here on, your belly will grow much rapidly in the coming weeks ahead. Not only that, you might be starting to feel aches in your abdomen as your round ligament stretches.

But the silver lining – You will be able to find out the gender of the baby on your next prenatal appointment next week!

During the next ultrasound, you will be able to see first hand, all the developments that you have been reading about here on BabyTalk.



How big is baby at 19 weeks? Your baby is the size of a mango, which is about 15cm (150mm).

The current weight of your baby is about 240grams (0.24kg).



This is the weight gain that you must achieve this week.

Underweight(BMI <18.5)  0.44kg to 0.58kg
Normal weight(BMI 18.5 to 24.9)0.39kg to 0.50kg
Overweight(BMI 25 to 29.9) 0.23kg to 0.33kg
Obese(BMI ≥ 30) 0.16kg to 0.25kg

During the second trimester, you will need to eat an extra 340 calories a day.



You’re in your second trimester! Congrats! And this also marks the end of morning sickness (for most mummies)and all the nasty symptoms that you experienced in your first trimester. However your body is still undergoing changes so you’re still not off the hook when it comes to pregnancy symptoms, unfortunately. 

Being 19 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Abdominal pains (Round ligament pain). As the muscles and ligaments stretch to accommodate the growing baby, you may notice pains and aches in the lower abdomen area.
  • Dark line across belly (Linea Negra). This darkened line runs from your belly button to your pubic bone, and is believed to be caused by the changing hormones or the imbalance of hormones. This occurs in about 75% of women and is a normal process of pregnancy.
  • Back pain. The weight of your uterus and growing baby will take a toll on your back as it gets heavier. Avoid standing for long periods of time and rest whenever you feel tired.
  • Dizziness.  During pregnancy, your blood pressure is lower, coupled with the fact that your growing baby is compressing your lungs. This combination results in less oxygen for you. Do take a slower and more comfortable pace if you find yourself having dizzy spells.
  • Skin changes. You will have patches of darkened skin which is a result of the increase in pigment. This is called chloasma, or the mask of pregnancy. Your palms may also be red as a result of the extra estrogen that your body is producing. 


Pay attention to every sensation in your belly, because it could just be your baby kicking, and you might mistake it for a normal body reaction.



Your baby has been moving around inside your belly for some time, but you didn’t feel it before because of the small size.

As he or she gets bigger, this is the time that you will be able to feel your baby moving about. Pay attention to every sensation in your belly, because you might mistake it for a normal body reaction.

Take care of your back as your belly gets heavier in the weeks to come. Do also ensure that you are putting on sufficient weight in the range as mentioned above. Sudden weight gain or weight loss is a cause for concern and if this happens, contact your doctor.



Your baby’s senses are developing really rapidly! The brain is developing the five senses – smell, taste, touch, sound and sight – for use when he or she is out of the womb.

Research suggests that the little one is now able to hear you, so sing or read to your baby to start building that parent-child bond.

Your baby can also sometimes be seen through the ultrasound; touching the amniotic sac, reaching for the umbilical cord, touching his or her face, sucking the thumb or crossing the legs. 

The kidneys are also producing urine and hair is starting to grow.

There is also a protective layer over the skin (vernix caseosa) now, which is a waxy and white substance. This substance is important because it helps to protect the baby’s delicate skin from the acid of the amniotic fluid and also helps ward off infections.



Reminders for the week:

  • Start reviewing infant care and child care options, because (believe it or not) there is a long waiting list.
  • Research on cord blood banking
