Pregnancy Phase — Trimesters & Clinical Care
Medical disclaimer: Educational content only, not medical advice. Test timing, screening thresholds, and delivery decisions must be individualized with your obstetric team.
This phase covers weeks 1–40+: fetal milestones, maternal changes, India clinical protocols (DIPSI, TIFFA, PMSMA), and multi-disciplinary deep research. Evidence tags: (a) settled consensus, (b) emerging/contested, © traditional with limited study, (d) popular claims with little support.
India clinical protocols: For PMSMA, DIPSI, TIFFA, supplement schedules, and government schemes, use the stage pages below. For developmental detail and gap patches, use the trimester research chapters.
Evidence tags: See the Evidence Rating Key on the reference overview.
