Week 37 marks the beginning of full-term pregnancy, signaling that the baby is ready for birth anytime with minimal health risks.
Understanding What Is Week 37?
Week 37 in pregnancy is a significant milestone. It’s the point where the baby is considered full-term, meaning the lungs and other vital organs have matured enough to function outside the womb. This week falls within the final stretch of pregnancy, often referred to as late preterm or early term, depending on medical definitions. At this stage, most healthcare providers consider delivery safe for both mother and baby, though many pregnancies continue up to week 40 or beyond.
This week brings a mix of anticipation and readiness. The baby’s growth is nearly complete, but subtle developmental tweaks continue. For mothers, physical symptoms may intensify or change as the body prepares for labor. Understanding what happens during week 37 helps expectant parents navigate this crucial phase with confidence.
Physical Development of Baby in Week 37
By week 37, your baby typically weighs around 6 to 6.5 pounds (2.7 to 3 kilograms) and measures about 19 inches (48 centimeters) long. The baby’s body has accumulated enough fat to regulate temperature after birth, giving that characteristic newborn plumpness.
The lungs are usually fully developed by this time, producing surfactant—a substance that keeps air sacs open and prevents breathing complications after birth. The brain continues maturing rapidly but has reached a stage where it can support basic functions outside the womb.
The baby’s skin smooths out as vernix caseosa—the protective waxy coating—thins but still covers much of the body to protect delicate skin from amniotic fluid exposure. Hair growth on the head varies widely; some babies are born with a full head of hair while others have very little.
Positioning and Movement
Most babies settle into a head-down position by week 37, preparing for delivery through the birth canal. This positioning is called vertex presentation and is ideal for vaginal birth.
Movements might feel different now—often less vigorous but more deliberate—as space inside the uterus becomes cramped. The baby’s kicks might feel sharper or more localized due to limited room.
Changes in Mother’s Body During Week 37
Pregnant individuals often notice increased physical discomfort by week 37. The uterus has grown substantially, putting pressure on surrounding organs such as the bladder and diaphragm.
Common symptoms include:
- Frequent urination: Pressure on the bladder intensifies as the baby drops lower.
- Braxton Hicks contractions: These “practice” contractions may become more noticeable and frequent.
- Pelvic pressure: As the baby descends into the pelvis (lightening), there’s increased pressure and sometimes pelvic pain.
- Fatigue: Carrying extra weight combined with disrupted sleep patterns can cause tiredness.
Hormonal shifts also continue to prepare the cervix for labor by softening and thinning it—a process called effacement—and gradually dilating it in some cases.
Nutritional Needs at Week 37
Nutrition remains crucial at this juncture. Caloric needs may increase slightly due to growing fetal demands and maternal energy expenditure during labor preparation. Maintaining balanced meals rich in protein, iron, calcium, and vitamins supports both mother and baby’s health.
Hydration is equally important since dehydration can trigger premature contractions or complicate labor onset.
Medical Monitoring and Tests Around Week 37
Healthcare providers ramp up monitoring during this period to ensure everything proceeds smoothly toward delivery. Prenatal visits often become weekly or biweekly after week 36.
Key assessments include:
- Cervical checks: To evaluate dilation and effacement progress.
- Fetal heart rate monitoring: Ensures baby’s well-being.
- Group B Streptococcus (GBS) screening: Typically done between weeks 35-37; if positive, antibiotics during labor help prevent infection transmission.
- Ultrasound scans: Sometimes performed to check amniotic fluid levels or fetal position.
Doctors also discuss birth plans during this time—covering labor signs, when to head to the hospital, pain management options, and possible induction scenarios if pregnancy extends beyond term.
The Importance of Recognizing Labor Signs
Knowing when labor begins is critical at week 37 since delivery could happen anytime now. Early labor signs include:
- Regular contractions: Increasing intensity and frequency that don’t subside with movement.
- Water breaking: Rupture of membranes causing fluid leakage.
- Bloody show: Pinkish or bloody vaginal discharge indicating cervical changes.
Promptly contacting healthcare providers upon noticing these signs ensures timely support and intervention if needed.
The Difference Between Early Term, Full Term & Late Term
Pregnancy duration classifications matter because they influence neonatal outcomes:
| Term Category | Pregnancy Weeks | Description & Risks |
|---|---|---|
| Early Term | Weeks 37-38 | The baby is generally healthy but may face slightly higher risks of respiratory issues compared to full term. |
| Full Term | Weeks 39-40 | The optimal period for delivery; babies born now usually have fully matured organs with minimal complications. |
| Late Term & Post-Term | Weeks 41-42+ | Babies may face increased risks such as decreased amniotic fluid or placental insufficiency; induction often considered. |
Week 37 marks entry into early term but is widely accepted as full-term enough for safe delivery if needed.
Mental and Emotional Changes in Week 37 Pregnancy
The emotional rollercoaster peaks around this time. Excitement mixes with anxiety about impending labor and parenthood responsibilities. Physical discomforts can exacerbate stress levels too.
Many expectant mothers experience mood swings fueled by fluctuating hormones combined with anticipation fatigue—wondering when labor will start or how it will unfold.
Support from partners, family members, or healthcare professionals plays a vital role here. Open communication about fears or expectations helps reduce tension while boosting confidence heading into childbirth.
Coping Strategies for Emotional Well-being
- Meditation & Breathing Exercises: Help calm nerves and improve focus.
- Prenatal Yoga: Combines gentle movement with relaxation techniques easing both body aches and stress.
- Talking It Out: Sharing feelings with trusted individuals provides relief from emotional burdens.
- Adequate Rest: Prioritize sleep whenever possible despite discomforts.
These approaches create balance during an intense phase before welcoming new life.
The Role of Partners During Week 37 Pregnancy
Partners often feel just as eager—and sometimes helpless—in these final weeks before birth. Their involvement can make a huge difference in easing maternal stress.
Simple gestures like attending medical appointments together offer reassurance through shared knowledge about progress and expectations. Helping manage household tasks reduces physical strain on pregnant partners while demonstrating care.
Encouraging open dialogue about fears related to labor builds emotional intimacy essential during this transition period.
Partners should also familiarize themselves with signs of labor onset so they can assist effectively when delivery time arrives—whether driving mom to hospital or providing comfort at home beforehand.
