📖 Week 28 Pregnancy — In-Depth Guide

Welcome to the third trimester — week 28 is a major milestone. Your baby can now open and close the eyes, has measurable REM sleep (the dreaming stage), and is gaining weight rapidly to prepare for life outside the womb.

From here, prenatal visits typically increase to every two weeks, and you will start doing daily kick counts to monitor your baby's well-being. These simple habits give you and your provider a clear picture of how your baby is doing.

Your baby now weighs over two pounds and measures about 38 centimeters. The brain is forming billions of neurons, the lungs are practicing breathing, and fat continues to smooth out the once-wrinkled skin.

👶Baby Development at Week 28

At 28 weeks your baby is about 38 centimeters long and weighs roughly 1,000 grams — just over two pounds, about the size of a large eggplant. The eyes can now open and close, and your baby experiences REM sleep, the stage associated with dreaming. Brain tissue is developing rapidly, forming the grooves and folds that support complex function.

The lungs are practicing breathing motions regularly and producing more surfactant, though they are not yet fully mature — babies born at 28 weeks usually need breathing support but have very good survival rates with modern neonatal care. Your baby's bone marrow is now fully responsible for red blood cell production, and the liver is storing iron for the first months after birth.

Your baby is also gaining fat quickly, which rounds out the body and regulates temperature after birth. The senses are well developed: your baby recognizes your voice, responds to light, and may even turn toward familiar music. Sleep-wake cycles are distinct, and you will likely notice favorite active times — many babies party hardest in the evening.

🩺Your Body: Common Symptoms at Week 28

The third trimester announces itself with unmistakable physical demands. Rest, support, and smart strategies make these weeks far more comfortable.

▸ Backaches

Now a near-constant companion for many. Maternity belts, warm baths, prenatal yoga, and good posture are your toolkit.

▸ Shortness of breath

The uterus crowds the lungs more each week. Move at a comfortable pace and sleep propped up if breathing feels tight at night.

▸ Heartburn

Often at its worst now. Small frequent meals, avoiding eating close to bedtime, and approved antacids help.

▸ Swollen feet and ankles

Expect daily swelling that improves overnight. Elevate your feet, stay hydrated, and report sudden severe swelling.

▸ Trouble sleeping

Between discomfort, kicks, and bathroom trips, deep sleep is elusive. Rest when you can and protect your sleep environment.

▸ Braxton Hicks contractions

Practice contractions may become more noticeable. They should be irregular and ease with rest — time them and call if they become regular.

▸ Leaking breasts

Colostrum, the nutrient-rich first milk, may leak from your nipples. Breast pads in your bra handle it discreetly.

▸ Vivid dreams

Hormones and anticipation fuel intense dreams. They are normal, even if they are strange — many pregnant women report them.

🏥Medical Tests & Checkups at Week 28

Week 28 brings several important medical items. If you are Rh-negative, you will receive the RhoGAM injection this week — it prevents your body from developing antibodies that could affect this or future pregnancies. You will get a second dose after delivery if your baby is Rh-positive.

Your provider will also do an antibody screen, check your iron levels for anemia, and may repeat tests for infections depending on your risk factors. If your placenta was low-lying at the anatomy scan, a follow-up ultrasound around now checks whether it has moved up.

Prenatal visits shift to every two weeks from here until week 36. Your provider will also teach you kick counting: choose a time when your baby is usually active, then count movements until you reach ten — most babies manage it well within two hours. Report it promptly if you notice a significant change in your baby's pattern.

🥗Nutrition & Movement Tips

In the third trimester you need about 450 extra calories a day — think an extra healthy meal's worth, focused on protein, whole grains, fruits, and vegetables. Your baby is gaining weight fast, and quality nutrition supports that growth plus your own stamina.

Iron needs peak now: the baby is stockpiling it, and your blood volume is at its highest. If your week-28 bloodwork shows anemia, your provider may recommend an iron supplement or dietary changes — take iron with vitamin C and away from calcium for best absorption.

Eat small, frequent meals to manage heartburn and keep energy steady. Keep drinking plenty of water, and limit caffeine as it can worsen sleep and heartburn.

Keep exercising as comfort allows — walking, swimming, and prenatal yoga remain excellent. Focus now on stamina, flexibility, and relaxation: practice labor breathing, try different labor positions (hands-and-knees, squatting with support, side-lying), and do your Kegels daily. Stop any activity that causes pain, dizziness, or contractions.

✅Week 28 Checklist

✓Get your RhoGAM shot if you are Rh-negative

✓Regular contractions before 37 weeks
✓Leaking fluid or vaginal bleeding
✓Severe headache, vision changes, or sudden swelling
