Dizziness can be caused by so many things thst it is not diagnostic. many women who are pregnant feel dizzy from time to time as the hormones and fluid balance of the body change.
Dizziness is one symptom of low blood pressure.
You should probably get checked out by your doctor, just to make sure that nothing too serious is wrong with you.
Best wishes.
