Common symptoms

  • Energy, appetite, sleep, and digestion may change.
  • Some people notice cramps, bloating, skin changes, or back discomfort.

  • Weeks 11-14: Nuchal translucency ultrasound if chosen and available.
  • Weeks 15-22: Second-trimester serum screening or AFP depending on prior screening choices.

Nutrition focus

  • Include protein, fiber-rich carbohydrates, colorful produce, and healthy fats.
  • Ask about iron, folic acid, iodine, vitamin D, choline, and omega-3 needs.
  • Follow local food-safety advice for fish, caffeine, unpasteurized foods, and supplements.

Warning signs

  • Call your care team for heavy bleeding, severe pain, fever, fainting, severe headache, vision changes, fluid leakage, or decreased fetal movement later in pregnancy.
  • Emergency symptoms should be handled urgently according to local medical guidance.
