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.
When to expect nausea during pregnancy. Nausea typically starts within four to eight weeks of gestation and is expected to subside between 13 and 14 weeks. However, it can start earlier and can last longer. Also, not every woman will experience nausea the entire duration of the first trimester. It could last only a couple of weeks or come and go throughout the first few months. Many refer to nausea during pregnancy as morning sickness, leading women to believe they will only experience nausea in the mornings.
