    Well nausea and vomiting is just normal during pregnancy, but the presence of hyperemesis gravidarum may signify that there is an abnormal thing that’s happening inside your during pregnancy. However, some mothers may experience it even during normal pregnancy. To make sure about your condition, it is better to seek regular prenatal check-ups to rule out any possible cause.
