Baby’s development at 19 weeks pregnant

Your baby has grown to about the size of a mango, measuring around 6 inches (15 cm) long and weighing about 8.5 ounces (240 grams).

Your body at 19 weeks pregnant

Your body is also going through many changes during this time. 

As your uterus grows, you may experience discomfort or pain in your abdomen, lower back, or pelvic area. You may also experience shortness of breath as your uterus expands and pushes against your diaphragm.

Other common physical pregnancy symptoms at 19 weeks may include:

  • Fatigue: As your body works hard to support your growing baby, you may feel more tired than usual. Physical discomfort and pain, such as round ligament pain around the lower back and abdomen, can also contribute to fatigue, so rest as much as you need. Prioritize self-care on your journey.
  • Constipation: Hormonal changes can slow down your digestive system, making it harder to have regular bowel movements. Drinking plenty of water and eating a fiber-rich diet can help.
  • Mood swings: The hormonal changes of pregnancy can also affect your mood, causing you to feel more emotional or irritable. Remember to be kind to yourself and seek support from loved ones or a healthcare provider. Pregnancy hormones cause a range of daily adverse symptoms such as mood swings, headaches, discomfort in the body, and emotional upheaval.
  • Baby bump: many women begin to notice a visible baby bump. The size and shape of the bump can vary depending on factors such as the woman’s height, weight, and body type, as well as the baby’s position in the uterus.

As you approach the halfway point of your second trimester, you must continue caring for yourself and your growing baby. 

This includes getting regular prenatal care, eating a healthy and balanced diet, staying active, and getting enough rest. Feel free to contact your healthcare provider with any concerns or questions.

Here are some tips for self-care for expecting mothers at 19 weeks pregnant:

1. Think about your diet

Eat various fruits, vegetables, whole grains, lean protein, and healthy fats. Consider taking a prenatal vitamin to ensure you get all the necessary nutrients.

Getting a good night’s sleep is essential for both your physical and mental health during pregnancy. Aim to get 7-8 hours of sleep per night and take naps during the day if needed. 

Remember to sleep on your side because sleeping on your back can overload your spine and compress major blood vessels.

4. Stay active

Regular physical activity is needed to maintain a healthy pregnancy and prepare your body for childbirth. 

Talk to your healthcare provider about what types of exercise are safe for you, and aim to get at least 30 minutes of moderate exercise most days of the week.

  1. Practice stress management:
  2. Take care of your skin

FAQs at 19 Weeks pregnant

Where is my baby at 19 weeks in my stomach?

Your baby is inside your uterus, behind the pelvic bones in the lower part of your abdomen. At this stage of pregnancy, your uterus has grown significantly and is now about the size of a cantaloupe, contributing to the shape of your pregnant belly.

Your baby is surrounded by amniotic fluid, which helps protect them and allows them to move around freely. The amniotic fluid also helps regulate your baby’s body temperature and provides a source of nutrition.

What organs are developed at 19 weeks?

At 19 weeks of pregnancy, many of your baby’s organs have already formed and are continuing to mature. Here are some of the major organs that are developed at this stage:

  1. Heart: By 19 weeks, your baby’s heart is fully formed and beating steadily. Your healthcare provider may be able to detect your baby’s heartbeat using a Doppler machine during prenatal check-ups.
  2. Brain and nervous system: Your baby’s brain is rapidly developing, and the nervous system is becoming more complex.
  3. Lungs: Your baby’s lungs continue to develop, producing surfactant, which helps the lungs expand and contract.
  4. Digestive system: Your baby’s digestive system is becoming more advanced, and its intestines are beginning to absorb small amounts of sugar from the amniotic fluid.
  5. Kidneys: Your baby’s kidneys function and releases urine into the amniotic fluid.
  6. Skin: Your baby’s skin is still thin and translucent but becomes more opaque as fat stores develop underneath. A white, waxy substance called vernix caseosa forms on your baby’s skin, made up of oil and dead skin cells from your baby.
  7. Bones: Your baby’s bones are beginning to harden and develop a skeletal structure.

At 19 weeks pregnant, your baby’s major organs have formed and are continuing to mature, and its body is growing and developing rapidly.

How do you know if something is wrong at 19 weeks pregnant?

At 19 weeks pregnant, it is crucial to be aware of any signs or symptoms that indicate something is wrong with your pregnancy. Here are some signs to look out for:

  1. Vaginal bleeding: Any vaginal bleeding during pregnancy should be reported to your healthcare provider immediately, as it can indicate a serious problem such as miscarriage, ectopic pregnancy, or placenta previa.
  2. Severe abdominal pain or cramping: While some mild abdominal discomfort is normal during pregnancy, severe pain or cramping could be a sign of a miscarriage, ectopic pregnancy, or other serious condition.
  3. Decreased fetal movement: If you notice a significant decrease in your baby’s movements or do not feel any activity for a prolonged period, it could be a sign of fetal distress.
  4. Leakage of amniotic fluid: If you experience a sudden gush from your vagina or a slow leak, it could be a sign that your amniotic sac has ruptured prematurely, which can lead to infection complications.
  5. High fever or infection: Any fever over 100.4°F (38°C) during pregnancy should be reported to your healthcare provider, as it can indicate an infection that can harm you and your baby.

Every pregnancy is different; some women may not experience any symptoms or signs of a problem at 19 weeks. 

However, if you have any concerns or questions about your pregnancy, it is always best to consult your healthcare provider for further evaluation and advice.

What should you avoid at 19 weeks pregnant?

At 19 weeks pregnant, there are several things you should avoid to ensure the health and safety of you and your growing baby. 

Certain Foods: Pregnant women should avoid foods that can increase the risk of foodborne illnesses, such as raw or undercooked meats, fish, and eggs. Also, it is advised to limit your caffeine and sugar intake.

Alcohol and Tobacco: It is recommended to avoid alcohol and tobacco during pregnancy as they can harm the developing fetus and lead to complications.

Medications: Certain medications can harm your growing baby, so it is essential to talk to your healthcare provider before taking any new medicines, including over-the-counter medications.

Hot Tubs and Saunas: Exposure to high temperatures from hot tubs, saunas, or steam rooms can be dangerous for the developing fetus and can increase the risk of neural tube defects, so it is recommended to avoid them.

Certain Activities: Activities such as contact sports or activities that pose a risk of falling or abdominal trauma, like horse riding or bungee jumping, should be avoided during pregnancy.

Chemicals and Toxins: Pregnant women should avoid exposure to certain chemicals and toxins, such as pesticides, lead, and mercury.

It is important to remember that every pregnancy is different, and what may be safe for one woman may not be safe for another. It is always best to consult your healthcare provider for specific guidance on what to avoid during pregnancy.

How many hours should a pregnant woman work on her feet?

There is no one-size-fits-all answer to this question, as the amount of time a pregnant woman can spend on her feet depends on several factors, such as her overall health, the stage of her pregnancy, the type of work she does, and her physical limitations.

That being said, it is generally recommended that pregnant women avoid standing for long periods, as this can increase the risk of varicose veins, swelling, and other discomforts. 

Pregnant women must take frequent breaks, stretch, and move around to reduce straining their feet and legs.

If you are pregnant and have concerns about your work or the amount of time you are spending on your feet, it is recommended that you talk to your healthcare provider for personalized advice and recommendations.

What to expect at a mid-pregnancy ultrasound?

A mid-pregnancy ultrasound, also known as an anatomy scan, is typically performed between 18 and 22 weeks of pregnancy. This ultrasound is a detailed scan that checks the development and growth of the baby, as well as the position of the placenta and the amount of amniotic fluid.

During the mid-pregnancy ultrasound, the sonographer or ultrasound technician will measure the baby’s head circumference, abdominal circumference, and femur length to determine the baby’s gestational age and ensure proper growth. The technician will also examine the baby’s organs, including the brain, heart, lungs, kidneys, and bladder, to ensure they are developing normally.

The mid-pregnancy ultrasound is an essential diagnostic tool to detect potential problems or abnormalities, such as neural tube defects, heart defects, or chromosomal abnormalities. 

Early detection of these issues can help healthcare providers plan for any necessary interventions or treatments. It can also give expectant parents important information about their baby’s health and well-being.

It is important to note that while mid-pregnancy ultrasounds are a routine part of prenatal care, they are not 100% accurate and may not detect all potential issues or abnormalities. 

Suppose you have any concerns or questions about the mid-pregnancy ultrasound or your pregnancy in general. In that case, speaking with your healthcare provider for guidance and reassurance is always best.


At this stage, many of the baby’s organs have already formed and are continuing to mature. You can also feel your baby more as it becomes more active. 

Regular prenatal care and self-care are crucial at this stage to ensure the health and safety of both mother and the growing baby. This includes attending prenatal check-ups, following a healthy diet and exercise regimen, getting enough rest, and avoiding harmful substances or activities. 

Being informed and prepared can help ensure a healthy and successful pregnancy.
