More than 50% of women experience morning sickness at some point during the first trimester of pregnancy. For many, the tell-tale nausea is the first indicator that they are pregnant. Though many experience morning sickness, the spectrum of what is considered “normal” sickness is vast.
Some women feel only vaguely unwell, while others suffer through frequent vomiting. Some mothers just feel bad in the morning; others feel terrible all day long. And of course, some women don’t experience morning sickness at all.
Though a certain amount of nausea is to be expected, if you experience excessive vomiting that prevents you from keeping your food down you need to tell your doctor. You may have hyperemesis gravidarum, a condition that can be harmful to both you and your baby.
I hope that helps, please post any questions you might have!
