Morning sickness can affect anyone who's pregnant. You might be more likely to experience morning sickness if:

  • You experienced nausea or vomiting from motion sickness, migraines, certain smells or tastes, or exposure to estrogen (in birth control pills, for example) before pregnancy
  • You experienced morning sickness during a previous pregnancy
  • You're pregnant with twins or other multiples
