Morning sickness can affect anyone who's pregnant, but it might be more likely 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

You might be more likely to experience hyperemesis gravidarum if:

  • You're pregnant with a girl
  • You have a family history of hyperemesis gravidarum
  • You experienced hyperemesis gravidarum during a previous pregnancy
