30 Weeks Pregnant

At a Glance: Week 30

Welcome to the three-quarter milestone of your pregnancy. At 30 weeks, you have about 10 weeks remaining. Your baby is approximately the size of a large head of cabbage, measuring around 39.9 cm (15.7 inches) and weighing roughly 1,320 grams (2.9 pounds). The week's key milestone: your baby's bone marrow has fully taken over red blood cell production from the liver and spleen, an important step in independent metabolic function. Your baby's brain continues rapid growth, body fat is accumulating, and weight gain accelerates from now until birth at about half a pound per week.

Your Baby's Development This Week

Week 30 brings several maturation milestones:

• Bone marrow: The bone marrow has fully taken over red blood cell production. This is a major step toward life outside the womb.
• Brain: The brain is still gaining hundreds of thousands of neurons each minute and continuing to develop folds and grooves. Brain weight is rapidly increasing.
• Lungs: Alveoli (the tiny air sacs that exchange oxygen) continue forming, and surfactant production increases significantly.
• Eyes: Your baby can now distinguish between light and dark, tracks moving lights, and may turn their head toward sources of light.
• Body fat: Brown fat continues to accumulate, which will help with temperature regulation after birth. Your baby's skin is becoming less wrinkled and more rounded.
• Lanugo: The fine downy hair (lanugo) that covered your baby's body is starting to shed as fat replaces its insulation role.
• Position: Your baby may be settling into a head-down position, though many still rotate over the next few weeks.

Your Body and Symptoms This Week

As you head deeper into the third trimester, symptoms cluster around the physical realities of carrying a rapidly growing baby. Common at 30 weeks:

• Carpal tunnel syndrome from fluid retention compressing the wrist nerve
• "Pregnancy brain" — forgetfulness and trouble concentrating
• Heartburn and reflux as your stomach is compressed
• Hip and pelvic pain as ligaments loosen further (relaxin hormone)
• Increased Braxton Hicks contractions
• Trouble sleeping from physical discomfort and hormone shifts
• Mild swelling in hands, feet, and ankles
• Frequent urination
• Itchy belly as skin continues stretching
• Stronger, more visible fetal movements

Nutrition: What to Eat and Avoid This Week

Continue eating roughly 450 calories above your pre-pregnancy baseline. The third trimester emphasis is on iron, calcium, omega-3s, and protein. Key focus this week:

• Iron (27 mg/day): Your bone marrow is producing red blood cells; your baby's is doing the same. Combine iron sources with vitamin C for absorption.
• Calcium (1,000 mg/day): Skeletal mineralization continues. Dairy, fortified plant milks, leafy greens.
• DHA (200–300 mg/day): Brain and retinal development. Low-mercury fish or algae oil.
• Protein (~71 g/day): Tissue growth and maintenance.
• Fiber (28 g/day): Helps with constipation and hemorrhoids. Whole grains, legumes, fruits, vegetables.
• Hydration: 2.3 liters (10 cups) of fluids per day reduces swelling, constipation, and Braxton Hicks.

Foods to avoid: high-mercury fish, raw or undercooked seafood and meat, unpasteurized dairy and juices, deli meats unless heated until steaming, raw sprouts, and alcohol. Keep caffeine below 200 mg per day.

Movement and Exercise

Most pregnant people can continue moderate exercise through 30 weeks with modifications. Aim for at least 150 minutes per week unless restricted by your provider. Good options:

• Walking — adjust pace and distance to comfort
• Swimming and water-based exercise — particularly helpful for back and pelvic pain
• Prenatal yoga and gentle stretching
• Stationary cycling (recumbent if balance is a concern)
• Pelvic floor strengthening (Kegels)
• Squats with support (prep for labor positions)

Avoid: contact sports, fall-risk activities, hot yoga or saunas, scuba diving, and lying flat on your back. Stop and call your provider for bleeding, contractions, fluid leakage, dizziness, chest pain, severe headache, or decreased fetal movement.

Mental and Emotional Wellbeing

Reaching 30 weeks can feel both thrilling and overwhelming. The reality that you will meet your baby in 8 to 12 weeks becomes harder to ignore. Anxiety often spikes around birth fears, parental capability, finances, and how your identity will shift. Sleep disruption amplifies all of this.

Practices that genuinely help:

• Childbirth education classes — knowledge significantly reduces fear of labor
• Identify your support network: who you can call at 3 AM, who can bring meals, who can help with older children
• Discuss postpartum mental health plans with your provider, particularly if you have a history of depression or anxiety
• Avoid comparison-driven social media use — every pregnancy and baby is different
• Practice 10 minutes daily of slow breathing, mindfulness, or gentle stretching
• Talk to your partner explicitly about how you each want to handle the first weeks at home

Common Concerns and When to Call Your Doctor

Continue daily fetal movement monitoring. Call your provider promptly for:

• Significant decrease in fetal movement
• Regular contractions (more than 4 per hour) or signs of preterm labor — menstrual-like cramps, low back ache, pelvic pressure
• Any vaginal bleeding
• Leaking fluid (clear, pink, or greenish)
• Severe headache not relieved by acetaminophen and rest
• Vision changes: spots, blurriness, flashing lights
• Sudden swelling in face or hands, or rapid weight gain
• Severe upper-right abdominal pain
• Calf pain, redness, or swelling (possible blood clot)
• Severe itching on palms or soles
• Fever above 38°C (100.4°F)

Tests and Appointments This Week

At week 30, you are typically between the standard GTT (24–28 weeks) and GBS screening (35–37 weeks). Your prenatal visit usually includes:

• Blood pressure screening for preeclampsia
• Urine sample for protein and glucose
• Fundal height measurement
• Fetal heart tones
• Discussion of fetal movement patterns
• Tdap vaccine if not yet given (recommended 27–36 weeks every pregnancy)
• Anti-D immunoglobulin (RhoGAM) if Rh-negative and not yet administered
• Growth ultrasound if indicated by clinical concerns (not routine at 30 weeks)

Visits remain every 2 weeks until 36 weeks, then typically weekly.

Tips for Week 30

• Try wrist splints at night if you have carpal tunnel symptoms.
• Make and freeze 5 to 10 easy postpartum meals on a slow weekend — your future self will thank you.
• Set up the baby's sleep space following safe-sleep guidance: firm mattress, no soft bedding.
• Schedule your Tdap vaccine if not already done.
• Write down questions as they come up between visits — pregnancy brain is real, lists help.

Preparing for What's Next

The next 10 weeks will move quickly. Use this stretch to:

• Install and inspect the infant car seat (free inspections are available through certified Child Passenger Safety Technicians)
• Pre-register at your birth facility if you have not already
• Finalize your pediatrician choice and confirm they accept your insurance
• Begin gathering hospital bag items so you can pack by 35 weeks
• Draft a one-page birth preferences document and review it with your provider
• If breastfeeding, attend a class and identify a local lactation consultant you could call after birth
• Discuss household division of labor for the first 6 weeks with your partner
