In the week 20, your baby is
the size of a Banana
Week 20 of pregnancy: Your baby is growing hair, kicking more, and you’re halfway through your journey!
Welcome to week 20 of your pregnancy journey! You're now halfway through, and your little one is growing by leaps and bounds. This week marks a significant milestone as your baby develops distinct features, and you may start feeling those magical first movements. Let's dive into the incredible changes happening with you and your tiny companion.
As your body continues to adapt to the growing baby, you may encounter some new symptoms:
Vaginal discharge
An increase in vaginal discharge is common due to hormonal changes. If the discharge is odourless and clear or milky white, it's likely normal.
Leg cramps
You may experience leg cramps, especially at night. Staying hydrated, stretching regularly, and massaging the affected area can help alleviate the discomfort.
Heartburn or indigestion
As your uterus grows, it pressures your stomach, leading to heartburn or indigestion. Eating smaller, more frequent meals and avoiding spicy or fatty foods may help.
Swelling
Swelling in the feet, ankles, and hands is common due to increased fluid retention. Elevating your feet and staying hydrated can help reduce swelling.
Itchy skin
As your skin stretches to accommodate your growing belly, it may feel scratchy, and you may notice stretch marks on your belly. Moisturising regularly can help soothe the itchiness.
Restless sleep
Finding a comfortable sleeping position may become more challenging. Sleeping on the side using a pregnancy pillow can provide support and improve sleep quality.
Shortness of breath
As your uterus expands, it can pressure your diaphragm, leading to shortness of breath. This is normal, but consult your doctor if it becomes severe.
At 20 weeks, your baby is making significant strides. Here's a closer look at your baby's development this week:
Organ Development
Your baby's digestive system produces meconium, a greenish-black substance that will accumulate in the bowels until birth. The brain is growing rapidly, especially in the nerve centres associated with the senses. The heart, kidneys, and other organs develop further, preparing your baby for life outside the womb.
Physical Features
Your baby's facial structures are becoming more defined, adding to its adorable features. Tiny nails are growing on the fingers and toes. The skin thickens and develops layers protected by a waxy coating called vernix.
Weight of the Foetus
At 20 weeks, your baby weighs around 250-310 grams, and the growth rate accelerates. The baby's weight is expected to increase steadily, with an average weekly gain of about 170 grams.
Movement of the Baby
This is often when mothers start to feel the baby's movements, known as quickening. These movements can feel like tiny flutters or rumblings in the tummy. Your baby is also developing a sleep-wake cycle and may respond to sounds in the environment.
At 20 weeks, your baby is at the halfway mark, growing stronger and more active each day. Their tiny heart pumps blood efficiently, and they’re beginning to develop a unique pattern of movement. It’s a remarkable stage where the bond between mother and baby deepens as you feel those first real kicks.
Your body is changing remarkably to accommodate and nourish your growing baby. Here's what you can expect:
Breast Changes
Your breasts may continue to enlarge and feel tender due to hormonal changes. The areolas may darken, and you might notice tiny bumps called Montgomery's tubercles around the nipples. These changes are preparing your breasts for breastfeeding.
Hair, Skin, and Nails
Pregnancy hormones can cause changes in your hair, skin, and nails. Your hair may become thicker and shinier, while your skin might be more sensitive to pigmentation changes and acne breakouts. Nails may grow faster but can also become brittle.
Respiratory and Cardiovascular System
As your uterus expands, it can pressure your diaphragm, causing shortness of breath. Your blood volume and cardiac output also increase to support the growing baby, which can lead to occasional palpitations. These changes are expected, but discuss any concerns with your doctor.
Vaginal Discharge
Increased vaginal discharge, known as leukorrhea, is common during pregnancy. It helps protect the birth canal from infections. If the discharge has a strong odour or causes irritation, consult your doctor.
Uterus Size and Position
At 20 weeks, your uterus has expanded towards your belly button, making room for your growing baby. You may start to show more prominently, and your maternity clothes might become your best friend.
Placenta Position
The placenta's position is checked during the 20-week ultrasound to ensure it is not covering the cervix (placenta previa), which could lead to complications later in pregnancy. Most often, the placenta is located on the upper or side wall of the uterus.
Stay active
Exercising during your pregnancy is encouraged, practice antenatal yoga or brisk walking.
Health check-in
Get your vaccinations and treat infections to prevent miscarriage or preterm labour
Stay active
A moderately intense 30-minute physical activity on most days of the week is great.
Take Prenatal Vitamins
Ensure you take prenatal vitamins throughout your pregnancy and the postpartum period
Routine visits
Schedule your check-ups every two weeks when 28–32 weeks and weekly from 32–40 weeks.
At 20 weeks, you will likely have a routine prenatal checkup and an anomaly scan:
Routine Check-Up
At 20 weeks, your healthcare provider will typically check your blood pressure, monitor weight changes, listen to your baby’s heartbeat, and answer any questions or concerns you may have.
Ultrasound
Your doctor may suggest the 20-week anomaly scan, an ultrasound that assesses your baby’s growth, amniotic fluid levels, blood flow, and any genetic or chromosomal anomalies. A fetal echocardiogram may be recommended to examine the baby's heart closely in case of any medical concerns.
Quadruple Screening Test
If not previously done, your doctor may offer the quadruple screening test this week based on your ultrasound results and risk factors. This blood test measures four markers—AFP, hCG, inhibin-A, and estriol—to assess the likelihood of conditions like Down syndrome, neural tube defects, or abdominal wall abnormalities.
Yes, feeling short of breath is common during pregnancy, especially as your uterus grows and puts pressure on your diaphragm. Practice good posture and take breaks when needed. However, if you experience severe breathlessness or chest pain, consult your doctor immediately.
Most women start to feel their baby's movements between 16 and 24 weeks of pregnancy. First-time mothers may not notice these sensations until closer to 25 weeks. The movements may feel like flutters, bubbles, or gentle kicks. As your pregnancy progresses, the movements will become more distinct.
Yes, the 20-week ultrasound can usually determine your baby's sex if you wish to know. However, keep in mind that the accuracy depends on factors like the baby's position and the clarity of the images. If you have a preference, let your sonographer know at the beginning of the scan.
In most cases, exercise is safe and beneficial during pregnancy. It can help manage weight gain, reduce stress, and prepare your body for labour. However, it's essential to choose safe activities and listen to your body. Avoid high-impact or contact sports and exercises that involve lying flat on your back. Walking, swimming, and prenatal yoga are great options. Always consult your doctor before starting or modifying your exercise routine.
A balanced diet rich in nutrients is crucial for your baby's growth and development. Include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats in your meals. Foods rich in folate, such as leafy greens and legumes, support brain and spinal cord development. Calcium-rich foods like dairy products and fortified plant-based milk help build strong bones. Avoid raw or undercooked meats, high-mercury fish, and unpasteurised dairy to minimise the risk of foodborne illnesses.
The recommended weight gain during pregnancy depends on your pre-pregnancy BMI. For women with a normal BMI (18.5-24.9), the general guideline is to gain 25-35 pounds (11-16 kg) throughout the pregnancy. Overweight women may aim for a lower range, while underweight women may need to gain more. Your doctor will offer personalised guidance based on your individual needs.
In most cases, travel is safe during the second trimester of pregnancy, provided you have no complications and feel comfortable. However, it's always best to consult your doctor before making travel plans. Long-distance travel, especially by air, may increase the risk of blood clots. Take frequent breaks to stretch your legs and stay hydrated. Avoid travelling to areas with a high risk of infectious diseases or limited medical facilities.
While light spotting can be normal during pregnancy, any bleeding or cramping should be reported to your doctor promptly. These symptoms could indicate complications such as placental issues or preterm labour. Your doctor will assess the situation and provide appropriate guidance and care.
