Prenatal care is one of the most evidence-backed interventions in all of medicine. Regular visits to your obstetrician throughout pregnancy allow for continuous monitoring of both mother and baby, early identification of potential complications, and timely intervention when needed. At Harsha Hospitals, our obstetrics team accompanies every patient through a structured antenatal programme that is both thorough and reassuring. Here is what you can expect at each stage.
First Trimester (Weeks 1–12): Establishing the Foundation
Your first antenatal appointment, ideally at 6 to 8 weeks, is one of the most comprehensive. Your doctor will confirm the pregnancy with an ultrasound, check the heartbeat, and determine the number of fetuses. Blood tests at this visit typically screen for blood group and Rh factor, complete blood count (to check for anaemia), thyroid function, blood sugar, rubella and hepatitis immunity, HIV, and sexually transmitted infections.
The booking appointment also covers a full medical history, current medications, and lifestyle counselling covering nutrition, safe exercise, and what to avoid during pregnancy. Between 11 and 13 weeks, a nuchal translucency ultrasound combined with a double or triple marker blood test screens for chromosomal conditions including Down syndrome — this early screening is an important step for all expectant mothers, regardless of age.
Second Trimester (Weeks 13–27): Detailed Monitoring
The anomaly scan, performed between 18 and 20 weeks, is often the most anticipated appointment of pregnancy. This detailed ultrasound examines the baby's anatomy — brain, heart, spine, limbs, organs — in careful detail, checks the position of the placenta, and measures the volume of amniotic fluid. Your doctor will also assess the cervical length to screen for risk of preterm labour.
A glucose challenge test between 24 and 28 weeks screens for gestational diabetes, which affects a meaningful proportion of pregnancies and, if undetected, can lead to complications for both mother and baby. From the second trimester onward, foetal growth and blood pressure are monitored at each visit, as pre-eclampsia (a pregnancy-specific condition involving high blood pressure and protein in the urine) often develops quietly without obvious symptoms.
Third Trimester (Weeks 28–40): Preparing for Birth
In the third trimester, visits increase in frequency — typically every two weeks from 28 weeks and then weekly from 36 weeks. Your doctor will monitor the baby's position (head-down is ideal for vaginal birth), assess foetal growth through fundal height measurement and growth scans, and check your blood pressure and urine at each visit.
A Group B Streptococcus (GBS) swab is typically taken at around 35 to 37 weeks, as this common bacterium can be transmitted to the baby during birth if present. Birth planning discussions, breastfeeding preparation, and signs of labour are all covered in the final trimester appointments.
Why Attendance Matters
It is tempting, especially in an uncomplicated pregnancy, to skip appointments when feeling well. The difficulty is that many of the most serious obstetric complications — gestational hypertension, foetal growth restriction, placenta praevia — present without symptoms and are detected only through scheduled monitoring. Each prenatal visit is both a safety check and an opportunity to ask questions, express concerns, and receive support. The relationship built between an expectant mother and her care team at these appointments is itself a therapeutic resource.
From the Harsha Hospitals team: Keep a written list of questions for each appointment — no concern is too small to raise. Bring your partner or a trusted support person when you can. And remember that missing even one scheduled visit means a gap in monitoring that cannot be fully recovered by the next. Your attendance is an act of care for your baby, and for yourself.
