Nausea and Vomiting in Pregnancy
What you are experiencing is most likely related to your pregnancy. However, if your vomiting is persistent and severe, you may have a condition called hyperemesis gravidarum.

Do you have severe and persistent nausea and vomiting and/or have you lost 5 percent or more of your body weight?
