This article will provide a comprehensive overview of what to expect when you are 30 weeks pregnant.

Common Symptoms at 30 Weeks Pregnant

Your body is working hard to help your baby grow during your third trimester. Here are some common symptoms and changes you may experience at 30 weeks pregnant:


  • Baby’s rapid growth: As your baby continues developing, you will really start showing now if you haven’t already. Your belly keeps expanding to make room for your growing baby.
  • Back pain: Your shifting posture and center of gravity as your belly grows can lead to back pain. Consider pregnancy pillows or gentle stretches.
  • Tiredness and trouble sleeping: It may be difficult to get comfortable as your belly grows. Try sleeping on your side, and take naps if needed.
  • Leg cramps: Muscle cramps in your calves or feet are common. Stretch before bed, hydrate, and get enough calcium and magnesium.
  • Braxton Hicks contractions: You may start feeling these “practice” contractions, which are irregular but painless tightenings.
  • Itching: Your expanding belly may cause itchy skin. Moisturize daily with creams to help prevent stretch marks too.
  • Dizziness: Your blood vessels are dilating, which can cause occasional lightheadedness or dizziness if you change position quickly. Take it slow.
  • Hemorrhoids: Constipation can cause painful hemorrhoids. Stay regular by eating fiber and drinking water.


  • Excitement and anxiety: As your due date gets closer, you may feel excited but also anxious about the challenges ahead. This is very normal!
  • Trouble concentrating: “Pregnancy brain” is common due to fatigue, hormonal changes, and being preoccupied with baby prep. Make lists and focus on one task at a time.
  • Mood swings: Hormonal changes can make your emotions feel like a rollercoaster. Take time for self-care and reach out for support from loved ones.

30 Weeks Pregnant Belly

Your uterus is now about 6 inches above your belly button, and you’ll really pop out now! Many women can no longer fit into their pre-pregnancy clothes and must wear maternity clothes. Support your bump with dresses, leggings, and comfortable shoes.

Your Growing Baby at 30 Weeks

Here’s what’s happening with your baby at 30 weeks pregnant:

  • Size: Your baby is about 15-17 inches long from head to toe – the size of a cabbage – and weighs around 3 pounds.
  • Developing lungs: Your baby’s lungs are developing branch-like structures called alveoli to prepare for breathing after birth. The lungs aren’t fully mature yet though.
  • Brain development: Your baby’s brain is developing rapidly. The wrinkles and grooves in the brain are forming to make room for all the growing nerves.
  • Opening and closing eyes: Your baby’s eyes have developed enough that they can actually open and close now!
  • Responding to stimuli: Your baby may react to loud noises or sudden movements from you by moving around. Their hearing is fully developed.
  • Swallowing amniotic fluid: Your baby is frequently swallowing the amniotic fluid around them, which contains nutrients and helps their digestive system develop.
  • Stronger bones: Your baby’s bones are becoming harder and less rubbery as calcium and phosphorus deposits build up.
  • Coordinating movements: Your baby is more gracefully coordinating hand-to-eye movements and movements overall thanks to brain and muscle development.

30 Weeks Pregnant Ultrasound

Around 30 weeks, your doctor may do an ultrasound to:

  • Check your baby’s growth and development
  • Look at your amniotic fluid levels
  • Determine your baby’s position
  • See your placenta location and umbilical cord blood flow
  • Check for any abnormalities or issues

The ultrasound technician will measure parts of your baby’s body to create an estimated fetal weight and check if your baby is measuring on track or far above/below average. Don’t be alarmed if not – some natural variation is normal.

You may be able to see your baby opening their eyes, yawning, sucking their thumb, and moving around during the ultrasound! Make sure to discuss the results with your doctor.

Prenatal Tests and Checkups at 30 Weeks

Here are some typical prenatal tests and appointments that happen around 30 weeks pregnant:

Group B Strep Test

Between weeks 35-37, your doctor will test you for Group B Streptococcus (GBS), the most common cause of life-threatening infections in newborns. The swab test is done during a regular prenatal visit. If you test positive for the GBS bacteria, you will get IV antibiotics during labor to prevent passing it to your baby.

Biophysical Profile Ultrasound

This ultrasound creates a “biophysical profile” to evaluate fetal well-being. It checks your baby’s breathing movements, body movements, muscle tone, and amniotic fluid level. If there are concerns, more tests or delivery may be recommended.

Regular Checkups

  • Fundal height measurement with a tape measure
  • Baby’s heart rate check
  • Your weight and blood pressure monitoring
  • Urine test for protein and infection
  • Symptoms discussion – prepare any questions!

Your doctor will monitor you and baby closely from now on to ensure you are both staying healthy and on track for the weeks ahead. Speak up about any concerning symptoms.
