Why Your 28-Week Ultrasound Marks a Special Milestone
Welcome to the third trimester! Around 28 weeks, your baby tips the scales at roughly 2.5 pounds and measures close to 15 inches (about the size of an eggplant). A “growth scan” at this stage offers an incredible look at your little one while confirming that both you and baby remain healthy.
What you’ll learn in this visit:
- Key measurements: head and abdominal circumference, femur length, estimated weight
- Developmental highlights: REM sleep, blinking eyes, first facial expressions
- Maternal health checks: placenta location, amniotic-fluid volume, Doppler blood-flow patterns
- Baby’s position: seeing how they’re lining up for birth
The scan itself takes about 30–45 minutes. At South Lake OB/GYN in Clermont, FL, our team uses advanced ultrasound technology and simple, friendly explanations so you leave feeling informed and reassured.
Pregnancy at 28 Weeks Ultrasound: What to Expect in the Scan
By now you’ve likely had an anatomy scan; today’s visit focuses on growth and well-being. Here’s a quick guide to the imaging types we may use:
| Ultrasound Type | Purpose | What You’ll See |
|---|---|---|
| 2D | Medical accuracy | Clear structures in B&W |
| 3D | Bonding & detail | Lifelike face photos |
| 4D | Real-time motion | Yawns, stretches, smiles |
| Doppler | Blood-flow check | Color patterns in cord & brain |
We’ll measure your baby’s head (BPD & HC), belly (AC), thigh bone (FL), then calculate an estimated fetal weight (EFW). Most 28-week babies land between the 10th and 90th percentile—what matters most is steady growth along their own curve.
Safety & Frequency
Extra scans are often ordered for:
- Fundal-height concerns (too big/too small)
- Low-lying placenta follow-up
- Twins or higher-order multiples
- Maternal conditions (gestational diabetes, hypertension)
- Notable changes in fetal movement
Ultrasound is considered safe when done by trained professionals. For a deeper dive into fetal testing, see intrauterine tests.
Decoding the Screen: Baby’s Milestones at Twenty-Eight Weeks

Your baby now weighs about 2.25 pounds and can open their eyes, experience REM sleep, and practice breathing movements. Lanugo (fine body hair) begins to shed, while cute fat layers fill out those cheeks. Deep ridges on the brain’s surface form crucial neural connections.
Pregnancy at 28 Weeks Ultrasound and Fetal Behavior Clues
During the scan you might spot:
- Tiny frowns or smiles
- Tongue movements as baby “tastes” amniotic fluid
- Rhythmic hiccups—a sign of a strong diaphragm
Twins & Multiples: Extra Checks
For multiples, we watch each baby’s growth curve, blood flow, and amniotic-fluid pocket. Differences greater than 20 % may prompt closer monitoring or earlier delivery. Learn more about twin care here.

Third-trimester self-care includes:
- Kick counts: Aim for 10 movements in two hours.
- Side-lying sleep: Preferably on the left, with pillows for support.
- Hydration: Eight glasses of water (or more if it’s hot or you’re swelling).
- Vaccines: Tdap between 27–36 weeks; Rh-negative moms get RhoGAM at 28 weeks.
- Pelvic support belts: Simple gear that eases back pain.
Getting Ready for Your Appointment
No full bladder needed—just wear comfy two-piece clothing and bring a support person if you’d like extra company. Create a quick question list so you don’t forget anything once you see that sweet face on the screen.
Navigating Results & Next Steps
Most parents leave the 28-week visit with great news, but if we spot anything concerning we’ll outline a follow-up plan—usually another growth scan in 2–4 weeks. Keep an eye out for signs of preterm labor such as regular contractions, pelvic pressure, or unusual discharge, and call us right away if they occur.
Even with normal results, now’s a perfect time to fine-tune your birth preferences and sign up for antenatal classes. And remember: emotional ups and downs are normal. If worries feel overwhelming, let us know so we can connect you with supportive resources.
Frequently Asked Questions about 28-Week Ultrasounds
How long does a 28-week scan take?
Plan on 30–45 minutes (a bit longer for twins or Doppler studies).
What if my baby is breech at this stage?
Plenty of time remains for baby to flip head-down. If breech persists after 36 weeks, we’ll discuss options such as an external version or cesarean delivery.
Do I need to fast or drink extra water beforehand?
No fasting, no gallon of water—eat and hydrate normally so you’re comfortable during the scan.
