Early in your first trimester, perhaps as early as eight weeks, you may feel dizzy and nauseous, because of low blood pressure. This happens because the pregnancy hormone progesterone relaxes the walls of your blood vessels, causing your blood pressure to fall (Bothamley and Boyle 2009). In the second and third trimesters, your growing uterus (womb) tends to put pressure on your blood vessels. This can also make you feel dizzy.
About half of pregnant women suffer from both nausea and vomiting, one quarter have nausea alone, and one quarter luck out altogether. The nausea usually starts around 6 weeks of pregnancy, but it can begin as early as 4 weeks.In fact, the technical medical term is nausea and vomiting of pregnancy.) For some pregnant women, the symptoms are worse in the morning and ease up over the course of the day, but they can strike at any time and, for most women, last all day long.
