Is normal to feel dizzy at 2nd trimester?

Hi mommies ❤️. This is my 2nd pregnancy. I'm currently at 13w+ . Doc give me aspirin. (Because my 1st baby 38weeks delivered but low birth weight, that y my gynae gave me aspirin to make blood thick n more flow to baby ) Do any mommies here same shoes with me? These past few days I feel dizzy. Try to take sugar n have rest . But still dizzy.
