Antenatal Care Trimester by Trimester: Tests, Visits & What to Expect

By Dr. Prithivi Perum, Obstetrician, Gynecologist, Fertility Expert & Laparoscopic and Robotic Surgeon at Mathrutva Women Healthcare, Manikonda, and Medicover Women & Child Hospitals, Hyderabad.

Quick answer: Good antenatal care means scheduled visits, timely scans, blood tests, vaccines, and open communication about symptoms. Each trimester has different priorities - confirming pregnancy health early, anomaly screening mid-pregnancy, and birth planning near term.

Dr. Prithivi Perum provides comprehensive maternal care at Mathrutva, Manikonda, with hospital support for delivery.

First Trimester (Weeks 1–12)

• Confirm pregnancy and dating scan
• Blood group, haemoglobin, sugars, thyroid, infections as advised
• Folic acid and prenatal vitamins
• Discuss prior pregnancy history and chronic illnesses
• NT scan window counselling around 11–14 weeks

Second Trimester (Weeks 13–26)

• Anomaly / TIFFA scan typically around 18–22 weeks
• Blood pressure and weight tracking
• Gestational diabetes screening as per protocol
• Feel for fetal movements later in this trimester

Third Trimester (Weeks 27–40)

• More frequent visits; growth and position assessment
• Birth plan discussion - normal labour vs caesarean indications
• Monitor blood pressure, swelling, and baby movements
• Hospital bag and emergency contacts ready

High-risk features need closer schedules - see high-risk pregnancy warning signs and pregnancy after 35.

Vaccines & Nutrition Basics

Tdap and influenza vaccines are important in pregnancy when recommended. Iron, calcium, and protein intake support mother and baby. Read vaccination in pregnancy.

“Antenatal visits are not paperwork - they are how we catch small problems before they become emergencies.”
