1. Late Growth Monitoring & Antenatal Surveillance

What parents often say

“We packed three hospital bags and still forgot the discharge file — the ‘when do we leave for the hospital?’ argument started every evening.” — composite of commonly reported experiences, not a named patient story.

Why it helps: Birth preparedness is logistics plus knowing labour signs, not just nesting. See also: Labour prep later on this page · Practical planning

A. Ultrasound Scans & Growth Trajectory

Third-trimester growth scans (typically performed between 28–32 weeks and repeated near term if indicated) evaluate:

  • Estimated Fetal Weight (EFW): Monitors fetal growth velocity to detect Intrauterine Growth Restriction (IUGR) or macrosomia.
  • Amniotic Fluid Index (AFI): Assesses fluid volume; screens for oligohydramnios (low fluid) or polyhydramnios (excess fluid).
  • Placental Location & Maturity: Confirms placenta is clear of the internal cervical os.
  • Doppler Velocimetry: Umbilical artery Doppler is conducted if growth restriction or preeclampsia is suspected.

B. Maternal Clinical Tracking

  • Blood Pressure & Proteinuria: Checked at every visit to detect late-onset preeclampsia.
  • Repeat Hemoglobin (Hb): Complete Blood Count is repeated at 28–32 weeks. Anemia can worsen in late pregnancy due to plasma volume expansion; iron supplementation is adjusted accordingly.

2. Fetal Movements — Maternal Safety Tracking

From 28 weeks onward, fetal movement serves as a direct indicator of fetal well-being:

Movement Pattern Principle: Every fetus develops a unique daily pattern of activity and rest. Movements are typically most noticeable when the mother is resting after meals. Rather than enforcing a rigid universal count, get accustomed to your baby's normal movement pattern.

Action Rule: If you notice a distinct decrease, sudden change, or absence of movement from your baby's normal pattern, lie down on your left side in a quiet room and count movements for 1–2 hours. If fewer than 10 movements occur, or if you feel concerned, contact your hospital casualty immediately for a Cardiotocography (CTG) check — do not wait until the next morning.

3. Group B Streptococcus (GBS) — Indian Clinical Practice

[!NOTE] Universal screening for Group B Streptococcus (GBS) via rectovaginal swab at 35–37 weeks (standard in US/UK guidelines) is not a uniform national protocol across public health facilities in India. Practice varies by hospital setting; private tertiary hospitals may offer screening, while others use a risk-factor approach (treating with intrapartum antibiotics if preterm labor, prolonged rupture of membranes >18 hours, or fever occurs). Ask your OB-GYN about your hospital's specific GBS protocol.

4. Labour & Birth — Comprehensive Reference

A. How Labour Begins

Understanding the signs of labour helps you decide when to head to the hospital:

Sign Description Action Required
True Labour Contractions Regular, painful tightening of the uterus that progressively becomes longer, stronger, and closer together (e.g., occurring every 5 minutes, lasting 60 seconds). Pain radiates from back to front and does not ease with rest or walking. Contact your doctor and head to your designated birthing facility.
Braxton Hicks Contractions Irregular, painless or mild tightening; stays localized in front; eases when you change position, walk, or drink water. Practice deep breathing; maintain hydration.
Rupture of Membranes (Water Breaking) Sudden gush or continuous trickling of watery fluid from the vagina. Go to the hospital immediately, regardless of whether contractions have started. Note the fluid color (clear vs. green/brown meconium stain).
Bloody Show Discharge of pink or brownish blood-tinged mucus (cervical mucus plug). Signals cervical softening; monitor for regular contractions.

B. Vaginal Birth & Delivery Stages

Vaginal birth progresses through three clinical stages:

  1. Stage 1 (Cervical Dilation):
  2. Latent Phase (0–5 cm): Cervix thins (effaces) and gradually opens. Contractions are mild to moderate.
  3. Active Phase (6–10 cm): Cervix dilates more rapidly; contractions become intense and frequent (every 2–3 minutes).
  4. Pain Management Options:
    • Epidural Analgesia: Local anesthetic injected into epidural space; provides effective regional pain relief while keeping the mother alert. (Availability varies by hospital tier).
    • Entonox (Gas & Air) / Parenteral Analgesia: Inhaled or injectable pain relief where epidural is unavailable.
    • Non-Pharmacological Relief: Upright positioning, birth ball exercises, warm showers, back massage, and rhythmic breathing techniques.

  5. Fetal Monitoring: Intermittent Doppler auscultation or continuous Cardiotocography (CTG) monitors fetal heart rate during contractions.

  6. Stage 2 (Pushing & Delivery of the Baby):

  7. Cervix is fully dilated (10 cm). The mother actively pushes with contractions as the baby descends through the birth canal.
  8. Episiotomy Guidance: FOGSI guidelines advocate for selective/restrictive episiotomy (surgical incision of the perineum) only when clinically indicated (e.g., fetal distress, rigid perineum, or instrumental delivery), rather than routine practice.

  9. Assisted Vaginal Birth: Vacuum extraction (ventouse) or forceps may be applied by the obstetrician if maternal exhaustion or fetal distress occurs during the pushing stage.

  10. Stage 3 (Delivery of the Placenta):

  11. Uterus contracts to detach and expel the placenta (typically within 5–30 minutes of birth). Oxytocin is administered to facilitate detachment and minimize postpartum hemorrhage.

C. Caesarean Section (C-Section)

A Caesarean section is the surgical delivery of the baby through abdominal and uterine incisions.

  • Planned (Elective) C-Section: Scheduled prior to labour due to known medical indications (e.g., complete placenta previa, transverse lie, past C-section with contraindication for VBAC).
  • Emergency C-Section: Performed during labour if acute complications arise (e.g., severe fetal distress, cord prolapse, placental abruption, failure of labour to progress).
  • Anesthesia: Regional anesthesia (Spinal or Epidural) is used in the vast majority of cases, allowing the mother to remain awake, painless, and conscious to greet her baby immediately. General anesthesia is reserved for rare emergency situations.
  • Post-Surgical Care & VBAC: Early mobility and wound care are initiated within 24 hours. Women with a single prior low-transverse C-section can discuss Trial of Labour After Caesarean (TOLAC/VBAC) for future pregnancies with their OB-GYN, depending on clinical criteria.

D. The Birth Partner's Role

A supportive birth partner (husband, mother, or companion) significantly improves the birthing experience:

  • Provide physical support: massage lower back during contractions, assist with position changes and birth ball use.
  • Encourage emotional calm and coach rhythmic breathing.
  • Offer ice chips or water sips during early labour.
  • Communicate the birthing woman's preferences to nursing and medical staff.
  • Maintain resilience and supportive calm if unexpected clinical decisions or transfers occur.

5. Birth Preparedness & Hospital Bag Checklist

Prepare your hospital bag by Week 34–36:

  • Hospital File & ID: Antenatal file containing all scans, blood reports, DIPSI results, blood group report, doctor prescriptions, and national ID (Aadhaar / health card).
  • Maternal Clothing: 3–4 front-opening nightgowns/kurtis for breastfeeding, supportive nursing bras, high-waist cotton underwear, maternity sanitary pads (heavy absorption).
  • Newborn Essentials: Soft washed cotton baby clothes (jhablas/onesies), baby caps, socks, soft baby swaddle towels, gentle baby wipes, newborn diapers, or cloth nappy sets.
  • Emergency Contact & Transport Plan: Save emergency transport numbers (108/102 ambulance under PMSMA/JSSK or private hospital emergency numbers); keep vehicle fueled.

[!CAUTION] Trimester 3 Warning Signs — seek emergency care immediately if you experience:

  • Severe headache, visual disturbances, upper abdominal pain, or sudden swelling (possible preeclampsia)
  • Vaginal bleeding or bright red spotting
  • Sudden gush or continuous trickle of fluid (possible rupture of membranes)
  • Distinct decrease or absence of fetal movement from your baby's normal pattern
  • Regular painful contractions before 37 weeks (possible preterm labour)
  • Severe shortness of breath or chest pain
