What Your Baby and Body Look Like at 20 Weeks Pregnant

Pregnancy brings a lot of changes to your life and body. As you progress through your pregnancy, your body will undergo a series of changes to accommodate your growing baby. At 20 weeks pregnant, you can expect physical changes such as pressure on your organs and the darkening of the linea nigra. Along with this, your baby is developing hair, eyebrows, and even — in the case of a girl — a uterus. Ultrasounds can help determine the size and position of the fetus, and at 20 weeks pregnant, your baby can hear sounds and may react to certain noises. Read on for a detailed overview of pregnancy body changes and the growth and development of your baby at 20 weeks pregnant.

Key Points of 20 Weeks Pregnancy

  • At this stage in your pregnancy, you'll begin to experience pressure on your organs from the growing baby that may cause physical discomfort.
  • An ultrasound can determine the size, position, and any other fetal abnormalities.
  • Your baby can hear sounds and may be startled by loud noises.
  • Indigestion and heartburn are common, which may make it difficult to eat larger meals.

Pregnancy Body Changes at 20 Weeks Pregnant

When you are 20 weeks pregnant, you may notice a darkening of the line between your belly button and pubic area (linea nigra). However, this will fade after delivery.

As your baby grows, pressure is being put on your lungs, stomach, bladder, and kidneys. This can cause frequent urination, shortness of breath with exercise, and indigestion or heartburn. You may also be perspiring more, as your thyroid is more active.

If you notice a vaginal discharge that is thin, milky-colored and has a slight odor do not be alarmed as this is normal. However, be sure to call your care provider if your discharge becomes thick and yellowish, very watery, or bloody. These could be signs of a more serious problem.

If you haven't already had one, your healthcare provider may recommend that you receive an ultrasound. This is a diagnostic test that uses sound waves to create an image. An ultrasound can determine the size and position of the fetus and any structural abnormalities of bones and organs that are visible along with the umbilical cord, placenta, and amniotic fluid.

Your Baby's Growth and Development at Week 20

When you are 20 weeks pregnant, your baby measures about 5.6 to 6.4 inches and weighs about 9 ounces. Your baby is starting to grow hair on his or her head, eyebrows are forming. And if your baby is a girl her uterus is now forming. Nail growth begins.

Your baby can hear sounds now, and it will cover its ears with its hands if a loud sound is made near you or move if it is startled.
