Week 38 marks the final stretch of pregnancy, where the baby is considered full-term and ready for birth.
Understanding What Is Week 38?
Week 38 of pregnancy is a crucial milestone in the journey toward childbirth. It represents the 38th week after the first day of the last menstrual period (LMP), placing it near the very end of a typical 40-week gestation. At this stage, the baby is classified as “full-term,” meaning it has developed sufficiently to thrive outside the womb without significant medical intervention.
This week is often filled with anticipation, as labor could begin at any time. For expecting mothers, knowing what to expect during week 38 helps prepare mentally and physically for delivery. The body undergoes several changes while the baby continues to fine-tune its development. Understanding these changes can ease anxiety and provide clarity on how labor might unfold.
Fetal Development in Week 38
By week 38, fetal growth has mostly plateaued, but important developmental refinements continue. The baby typically measures about 19 to 20 inches long and weighs roughly 6.5 to 7 pounds, though individual sizes vary. The skin appears less wrinkled than in earlier weeks due to fat accumulation beneath it, which helps regulate body temperature post-birth.
The lungs are fully mature by this point, producing surfactant — a substance that prevents lung collapse after the first breath. This readiness is critical because lung immaturity is a common cause of complications in premature babies.
Additionally, the baby’s brain continues rapid growth and development, increasing neural connections that support cognitive and motor functions after birth. The digestive system is functional but will now rely on external feeding rather than placental nutrients.
The immune system also strengthens as antibodies transfer from mother to baby through the placenta, providing early protection against infections.
Physical Positioning of Baby
Most babies settle into a head-down position by week 38, known as vertex presentation, which facilitates a smoother vaginal delivery. However, some babies may remain breech (feet or buttocks first) or transverse (lying sideways). These positions can complicate delivery and may necessitate cesarean section.
The baby’s movements might feel different now—less vigorous but more rhythmic—as space inside the uterus becomes limited. These movements are reassuring signs of fetal well-being.
Maternal Changes During Week 38
Pregnant individuals experience pronounced physical changes during week 38. The uterus reaches its maximum size, pressing against internal organs such as the bladder and diaphragm. This pressure causes frequent urination and sometimes shortness of breath.
Braxton Hicks contractions—irregular tightening of uterine muscles—may become more noticeable but do not signify true labor unless they increase in intensity and frequency.
Many women notice increased vaginal discharge or “bloody show,” indicating cervical changes preparing for birth. The cervix softens (effacement) and begins to dilate slightly in some cases.
Swelling in feet and ankles can intensify due to fluid retention and reduced circulation from uterine pressure on blood vessels. Staying hydrated and elevating legs can help alleviate discomfort.
Hormonal shifts continue as oxytocin levels rise, stimulating uterine contractions when labor begins naturally.
Emotional Impact at Week 38
Emotions often run high during this final stretch. Excitement mixes with anxiety about labor pain, delivery outcomes, and newborn care responsibilities. Sleep disturbances become common due to physical discomforts like frequent urination or back pain.
Support from partners, family members, or healthcare providers proves invaluable during this time to manage stress effectively.
Signs Labor Could Begin Soon
Recognizing early signs of labor around week 38 helps pregnant individuals seek timely medical care and avoid unnecessary panic.
Common indicators include:
- Regular contractions: Unlike Braxton Hicks contractions, true labor contractions occur at consistent intervals that gradually shorten.
- Water breaking: Rupture of amniotic sac releasing fluid signals imminent labor.
- Cervical dilation: Progressive opening of cervix measured by healthcare professionals.
- Increased pelvic pressure: Baby’s descent into birth canal causes sensation of heaviness or pressure.
- Bloody show: Pinkish mucus discharge resulting from cervical changes.
If any of these signs appear suddenly or intensify rapidly, contacting healthcare providers immediately is essential for safety.
The Importance of Prenatal Visits at Week 38
Prenatal appointments become more frequent as pregnancy nears term—often weekly after week 36—to monitor both maternal and fetal health closely.
During these visits:
- Fetal heart rate: Monitored via Doppler device to ensure normal patterns.
- Belly measurements: Check for appropriate growth trajectory.
- Cervical exams: Assess dilation and effacement progress.
- Blood pressure monitoring: Detect early signs of preeclampsia or other complications.
- Urine tests: Screen for infections or proteinuria.
Doctors may also discuss birth plans, pain management options during labor, and post-delivery care during these visits.
Preparing for Delivery During Week 38
Expectant parents often use this time to finalize hospital bags, arrange transportation plans for labor onset, and review birthing preferences with their medical team.
It’s wise to discuss potential scenarios such as induction if labor doesn’t start naturally within a certain timeframe or cesarean delivery if complications arise.
Taking childbirth education classes before this week can provide useful coping techniques for pain management and breathing exercises during contractions.
Nutritional Needs in Week 38
Maintaining balanced nutrition remains vital at this stage to support energy levels required for childbirth and postpartum recovery.
Focus on:
- Protein-rich foods: Aid tissue repair after delivery.
- Iron sources: Prevent anemia common in late pregnancy.
- Dairy products or alternatives: Provide calcium necessary for bone strength.
- Hydration: Essential for overall well-being; dehydration can trigger contractions prematurely.
Avoid excessive caffeine or high-sodium foods that may increase swelling or affect sleep quality negatively.
A Closer Look: Fetal Growth Data at Week 36 vs Week 38 vs Week 40
| Gestational Week | Average Weight (lbs) | Average Length (inches) |
|---|---|---|
| Week 36 | 5.8 – 6.0 | 18 – 19 |
| Week 38 | 6.5 – 7.0 | 19 – 20 |
| Week 40 (Full Term) | 7.5 – 8.0 | 19 – 21 |
This table highlights how fetal weight gain slows down near term while length increases slightly as development completes before birth.
The Role of Medical Interventions Around Week 38
While spontaneous labor is ideal around week 38-40, medical interventions sometimes become necessary based on maternal or fetal health conditions:
- Labor induction: Initiated if overdue pregnancy risks outweigh waiting; methods include medications like oxytocin or membrane stripping.
- Cerclage removal:If cervical stitches were placed earlier due to risk factors; removal typically occurs near term.
- C-section planning:If breech position persists or other complications arise preventing safe vaginal birth.
- Preeclampsia management:If high blood pressure worsens dangerously close to delivery time.
These interventions aim to optimize outcomes but require thorough discussion between patient and healthcare provider regarding benefits versus risks.
The Significance of Understanding What Is Week 38?
Grasping what happens during week 38 empowers expectant mothers with knowledge about their bodies’ signals and their baby’s readiness for life outside the womb. This awareness reduces uncertainty surrounding late pregnancy symptoms and supports informed decision-making regarding labor onset timing or hospital visits.
Healthcare teams emphasize individualized care since every pregnancy progresses uniquely; however, recognizing common patterns around week 38 sets realistic expectations while preparing families emotionally and logistically for childbirth’s arrival.

Many women report feeling overwhelmed by sudden mood swings linked to hormonal surges combined with anticipation fatigue—waiting anxiously yet dreading intense labor pains ahead.
Open communication with loved ones eases feelings of isolation that sometimes accompany late pregnancy stages; sharing hopes fears creates supportive bonds essential during this transformative phase before welcoming new life into the world.
