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.
Reasons You Might Get Dizzy. One of the things that changes drastically in pregnancy is how much cardiac output ramps up. This can increase up to 30-50% in pregnancy and starts fairly early on in gestation. As your body adapts to pregnancy, your heart works harder and you have more blood volume to take care of your needs and the needs of your baby.
