Antenatal Checkup Schedule & Pregnancy Scans
First Trimester Checkups (Weeks 1 to 12)
The initial antenatal visit confirms intrauterine pregnancy, calculates estimated gestational age, and records baseline blood pressure and maternal weight.
Essential tests include blood grouping, Rh factor, hemoglobin, blood sugar, thyroid profile, infectious disease screening, and the 11-13 week Nuchal Translucency (NT) ultrasound scan.
Second Trimester Scans & Monitoring (Weeks 13 to 28)
Routine visits occur monthly. The detailed Anomaly Scan (TIFFA) conducted between 18 and 22 weeks evaluates the baby's brain, heart, kidneys, spine, and limb structures.
Oral glucose tolerance testing (OGTT) is performed between 24 and 28 weeks to screen for gestational diabetes.
Third Trimester Preparation (Weeks 28 to 40)
Visits increase to bi-weekly from week 28 to 36, and weekly from week 36 onward. Growth Doppler ultrasound scans assess amniotic fluid volume and blood flow to the placenta.
Mothers receive birthing plan counseling, pelvic assessment, and pain management options including epidural labor.
