20 weeks pregnant symptoms

Week 20 can bring a mix of physical and emotional changes. After 20 weeks, certain pregnancy complications may be diagnosed such as preterm labor, gestational diabetes, or preeclampsia. Here are some common symptoms at this stage:

Increased appetite: As your baby grows, you may find yourself feeling hungrier than usual, so focus on nutrient-rich foods.
Stretch marks: As your belly expands, some women may start to notice stretch marks on the stomach, thighs, or hips.
Shortness of breath: As the uterus grows, it can press on the diaphragm, causing mild shortness of breath, especially after physical activity.
Frequent urination: With the baby and uterus putting pressure on the bladder, you may feel the need to urinate more often.
Baby movements: Many women experience regular baby movements called quickening, especially after meals or during quiet times.

Your body at 20 weeks pregnant

At 20 weeks, your uterus is continuing to grow, reaching just below your belly button, and making your bump more defined. You may also notice physical changes like weight gain and some new stretch marks. Using a pregnancy weight gain calculator can help you monitor healthy weight gain. Hormonal shifts can affect your skin, so staying hydrated and using moisturizer can be beneficial. Since you’re halfway through your pregnancy, this is a good time to check in with your healthcare provider to discuss weight gain and overall health, ensuring you’re on track for the remainder of your pregnancy.

20-week pregnant belly

By week 20, your belly may feel firmer and more rounded, with a prominent bump as your uterus expands upward. Many women find that maternity clothes are more comfortable by this stage, and your growing bump may attract attention from friends and family excited for your journey.

Baby development at 20 weeks pregnancy

At 20 weeks, your baby’s growth is marked by increased muscle development and improved coordination. They’re practicing essential reflexes and may be more active, especially in response to external sounds. Their senses are also developing, allowing them to hear your heartbeat and the muffled sounds of your voice. A layer of fine hair, known as lanugo, covers their body, helping to regulate temperature as they grow. The nervous system is maturing, and the baby’s movements become more coordinated, allowing them to kick, stretch, and even roll.

20-week baby size

The 20-week baby size is around 6.5 inches long and weighs approximately 10.5 ounces, comparable to the size of a banana. This week marks a period of rapid growth as your baby continues to develop essential systems and functions.

20-week ultrasound

The 20-week ultrasound is often called the anatomy scan, providing a detailed look at your baby’s organs, spine, and limbs. During a 20-week ultrasound 3D or 4D scan, you may see a clearer view of your baby’s face, hands, and feet. The ultrasound technician may also be able to confirm your baby’s gender if you choose to find out. This scan is an important milestone, allowing healthcare providers to ensure your baby is growing and developing well.

Position of a baby in the womb at 20 weeks

At 20 weeks, your baby still has plenty of room to move, so their position can change frequently. The baby may be head-down, breech, or even sideways. As pregnancy progresses, the baby’s position will become more consistent in preparation for birth.

Tests to expect at 20 weeks of pregnancy

20-week anatomy scan: A comprehensive ultrasound that provides detailed insights into the baby’s development, including heart, brain, spine, and other vital organs.
Regular checkups: Expect a check on your blood pressure, weight, and urine to monitor for signs of preeclampsia or infection. As your pregnancy advances, your office visits may become more and more frequent as you approach the term.
Fundal height measurement: Your healthcare provider may start measuring fundal height, which assesses fetal growth by measuring from the pubic bone to the top of the uterus.
