What causes dizziness during pregnancy? The main cause of dizziness in pregnancy is due to the rising hormones that cause your blood vessels to relax and widen. This helps increase the blood flow to your baby, but it slows the return of the blood in the veins to you.
However, generally dizziness in pregnancy usually occurs in the second or third trimester. Dizziness is not a classic symptom of pregnancy. Typical symptoms of pregnancy include one or more missed periods (amenorrhea), breast tenderness, nausea or vomiting, and urinary frequency.
