At 38 weeks, your baby is considered full term. Their lungs are ready, their digestive system is fully developed, and their brain keeps growing. Every body system is developed and functioning, which means labor is safe to begin any time now.
Waiting out these last few days is genuinely hard. Week 38 is when most parents find themselves watching the clock, second guessing every small cramp, wondering if today is the day. The car seat is fastened in, the hospital bag sits by the door, and life feels like it is on pause. Knowing exactly what is happening inside your bump right now brings real comfort, and it lets you step into these last stages with a bit more confidence.
Key Baby Development Milestones In Week 38 Pregnancy
Reaching 38 weeks shifts your medical status completely. OB GYNs and midwives officially classify this as full term.
Your baby has moved past basic organ building. Now their body is focused on stocking up quick energy reserves and sharpening automatic survival reflexes.
Physical Size And Weight Gains
A baby at 38 weeks usually weighs somewhere between 6.8 and 7.2 pounds and measures about 19 to 20 inches long, roughly the size of a large winter squash.
- Adding protective fat: your baby is putting on roughly half an ounce of fat each day. That fat fills out wrinkly skin and helps keep their body temperature steady once they are born.
- Shedding vernix and lanugo: the protective cheesy coating (vernix) and fine body hair (lanugo) start dropping off into the amniotic fluid.
- Soft skull bones: their bones are hardening, but the skull plates stay loose. That natural flex lets the head slip safely through the birth canal.
Many parents start planning ahead for feeding around now too. It is worth exploring options like freeze dried breast milk powder so you have your setup sorted before labor begins.
Internal Organ Readiness
Every main system inside your baby's body is rehearsing for the birth day.
- Lungs and breathing: the lungs keep pumping out surfactant so the air sacs do not stick shut during that first real breath.
- Brain and nervous system: nerve connections are multiplying fast. Simple reflexes, like blinking, gripping tight and swallowing, are fully functional.
- Digestive system: swallowing amniotic fluid leaves behind meconium in the intestines, which becomes that very first sticky diaper change.
Common Physical Symptoms And Labor Signs At 38 Weeks
Carrying a full term baby gets heavy. As your baby drops lower into your hips, the physical signals get much harder to miss.
Early Signals That Delivery Is Near
Labor rarely looks like it does in the movies. It usually starts with quiet, subtle changes over a few days.
- Lightening (baby drops low): your baby settles deep into your pelvis. Pressure eases off your lungs, so breathing gets easier, but your bathroom trips double.
- Losing the mucus plug: the protective seal on your cervix loosens as things stretch. It looks like a clear, pink, or brownish jelly like discharge on toilet paper.
- Digestive shifts: hormones loosen muscles across your whole body right before labor, which can bring on mild nausea or loose stools.
Learning the basics of early infant feeding is a good way to stay productive during this waiting window too. Knowing how long expressed milk can safely sit out at room temperature, for instance, means you are ready for those middle of the night feeds.
Braxton Hicks Versus Real Labor Contractions
Telling practice cramps apart from true labor comes down to three clear markers.
|
Feature |
Braxton Hicks |
True Labor |
|
Timing and pattern |
Irregular, sporadic, never forms a fixed pattern |
Regular, predictable, gets steadily closer together |
|
Intensity |
Mild to uncomfortable tightness that stays weak |
Starts like deep menstrual cramps and grows progressively stronger |
|
Effect of movement |
Drinking water, resting or taking a shower stops them |
Keeps tightening regardless of position shifts or rest |
|
Location of pain |
Felt mainly across the front of your stomach |
Starts in your lower back and wraps around your entire torso |
Essential Medical Checks During Week 38 Doctor Visits
Weekly checkups are standard at 38 weeks to keep a close eye on you and your baby.
Standard Tests And Evaluations
- Blood pressure and urine (protein) checks: these help catch early signs of pre eclampsia.
- Fetal position check: your provider gently presses on your belly to check that baby is head down.
- Heart rate tracking: a brief doppler scan checks your baby's pulse and how well they are adapting inside the womb.
- Optional cervical exams: your provider may offer a brief check to see whether your cervix is softening, thinning (effacement), or opening (dilation).
This stage is also a good time to look into longer term feeding basics, like reading up on breast milk storage or exploring general feeding care at Wonderbewbz.
What About If The Baby Is Breech?
At 38 weeks, if your baby is sitting feet first or bottom down, your provider will talk through your options. Some mums try an external cephalic version, which involves gently rotating the baby from outside the body, while others opt for a scheduled cesarean.
Action Plan: Preparing For Arrival At 38 Weeks
Getting practical tasks out of the way now cuts down on the panic once contractions start.
Practical Hospital Checklist
- Pack the hospital bag: keep essentials ready near the front door, including comfortable clothes, toiletries, phone chargers and baby outfits.
- Check the car seat: make sure the infant seat is buckled correctly into the back seat and checked by a safety technician.
- Set up a recovery spot: prepare a quiet room at home with extra pillows, water bottles, simple snacks and postpartum supplies.
- Track fetal movement: pay attention to your baby's daily patterns. Aim to feel at least 10 distinct kicks or rolls within a quiet two hour window.
Simple Comfort Strategies For The Final Days
- Elevate legs daily: prop your feet up on cushions while sitting to ease swelling in your feet and ankles.
- Use a maternity belt: a soft belly support band lifts weight off your pelvic bone during short walks.
- Take warm baths: soaking in a warm tub relaxes tight hip joints and takes weight off your lower back.
While you are resting, it is worth reading up on post birth milk storage too, like how long breast milk keeps in the fridge, just to build a bit of confidence for life at home.
Summary Of Week 38 Pregnancy
At week 38, you are almost at the end of the line. Your baby is ready for birth, their lungs are ready to function, their reflexes are active, and their protective fat stores are in place.
Staying aware of the signs of labor, keeping up with your weekly checks, and resting when you can will help you feel confident and prepared for delivery day.
Frequently Asked Questions
Can a baby be considered full term if born in week 38?
Yes. Early term birth is medically defined as 38 weeks, and full term begins at 39. A baby born at 38 weeks has fully developed organs and is ready for life outside the womb.
How many months pregnant is week 38?
Week 38 sits right in the middle of your 9th month.
Where should the baby be positioned at 38 weeks?
Head down, facing toward your spine, is the ideal position. It lets your baby move through the pelvis far more smoothly during birth.
What causes sudden pain in the pelvis at 38 weeks?
Those sharp pains come from your baby's head pressing directly against low pelvic nerves and joints as they settle lower into position.
Can labor begin suddenly without early warning signs?
Yes. While many people notice gradual signs like losing the mucus plug, active labor can also start out of nowhere with strong contractions or your water breaking.
When is it time to head to the hospital?
Most providers suggest heading in once contractions arrive 5 minutes apart, last a full minute each, and hold that pattern for a full hour straight.
Can walking help bring on labor during week 38?
Walking uses gravity to nudge your baby's head deeper against your cervix. That pressure can help encourage natural labor hormones once your body is ready.
What does losing the mucus plug look like?
Usually a thick, jelly-like blob of discharge. The color ranges from clear and white to pinkish or light brown.
Is sudden face or hand swelling normal at week 38?
Mild ankle swelling is normal, but sudden puffiness in your face, hands, or around your eyes needs immediate medical review to rule out pre eclampsia.
What should I do if the baby's movements slow down at 38 weeks?
Your baby's movement should stay active. If it feels slower than usual, drink cold water, lie on your left side, and count kicks. Contact your provider right away if movement stays low.
