Pregnancy by Trimester — First, Second and Third
Pregnancy unfolds in three trimesters, each with its own clinical questions, monitoring priorities, and supportive needs. First-trimester care confirms viability, screens for early complications, and establishes the baseline pregnancy profile. Second-trimester care includes the anomaly scan and routine screening tests. Third-trimester care monitors growth, prepares for delivery, and addresses late complications when they arise. The transition between trimesters is not a hard line — but the care priorities meaningfully shift.
Our approach to trimester-by-trimester care
Every pregnancy at Balaji Horizon is monitored on a structured schedule calibrated to risk profile — RCOG schedule for low-risk pregnancies, with additional checkpoints added for any identified risk factors. We discuss what to expect at each visit before the visit, so patients know what is happening and why.
First-trimester care (weeks 1–12)
Dating scan, viability confirmation, baseline bloods, screening discussion (NT scan + combined screening or NIPT), nutritional and lifestyle counselling. Early pregnancy is also when many anxieties peak — we provide accessible answers between visits.
Second-trimester care (weeks 13–27)
Anomaly scan (typically 18–22 weeks), gestational diabetes screening, fetal movement counselling, continued blood pressure and weight monitoring. The mid-pregnancy phase is when many patients begin to feel more confident — we maintain monitoring without manufacturing anxiety.
Third-trimester care (weeks 28–40)
Growth scans, blood pressure surveillance for preeclampsia, group B strep discussion, delivery planning conversations, birth preferences, breastfeeding preparation. The frequency of visits increases through the third trimester.

The three trimesters
| Trimester | Weeks | Focus |
|---|---|---|
| First | 1–12 | Confirm, dating, NT scan |
| Second | 13–27 | Anomaly scan, growth |
| Third | 28–40 | Growth, position, birth planning |
Where this fits
Trimester care intersects with fetal medicine at scan checkpoints, with screening tests at specific gestations, and with high-risk care if risk factors emerge.
