You’re more likely to have nausea or vomiting during your pregnancy if:
- You’re pregnant with twins. This may be from the higher levels of hormones in your system. You’re also more likely to have a more severe case of morning sickness. But, some women carrying twins have little or no nausea.
- You had morning sickness in a previous pregnancy.
- You have a history of nausea or vomiting as a side effect of taking birth control pills. This is probably related to your body’s response to estrogen.
- You have motion sickness.
- You have migraine headaches.
- If your mother or sisters had severe morning sickness, there’s a higher chance you will, too.
- You’re carrying a girl. Women with severe nausea and vomiting were 50% more likely to be carrying a girl.
