All four topics are covered! Here's a quick orientation to what you just got:

What's Covered - Quick Map

Topic 1 - Diagnosis of Pregnancy: All three categories (presumptive, probable, positive signs) with named signs (Hegar's, Goodell's, Chadwick's, Ballottement, etc.), hCG levels and timing, and USG dating.
Topic 2 - Vomiting in Pregnancy: Normal NVP vs Hyperemesis Gravidarum, full differential diagnosis (very exam-favourite), investigations, and stepwise treatment including which drugs are safe (ondansetron, doxylamine+pyridoxine) and the Wernicke's complication.
Topic 3 - Hemorrhage in Pregnancy: Full coverage of APH (placenta previa vs abruption with a comparison table), plus PPH with the "4 Ts" and management ladder.
Topic 4 - Development: Placenta (implantation, primary-secondary-tertiary villi progression, functions), embryo (germ layers, gastrulation, primitive streak), amniotic fluid (volumes by week, poly vs oligo causes/complications), and umbilical cord (structure, all major abnormalities including vasa previa).
High-yield exam tips to keep in mind:
  • The placenta previa vs abruption comparison table is almost always in exams
  • hCG peaks at 8-10 weeks = ~100,000 IU/L, then falls
  • SUA = always screen for other anomalies
  • Vasa previa = painless bleed at rupture + sudden fetal bradycardia = emergency CS
  • Potter sequence = bilateral renal agenesis → oligohydramnios → pulmonary hypoplasia
  • Wernicke's encephalopathy = complication of prolonged HG (give Vitamin B1/thiamine)
Good luck tomorrow! You've got this.
