Anemia

Has anyone been detected with anemia in your pregnancy? What were your symptoms? I have a history of having horrible anemia as a little kid...and now some symptoms have came back. I am excessively tired, I can barely get up and make food. I feel dizzy and lightheaded. I used to wake up starving... And now i don't even wake up hungry. I am 15 weeks, I got tested for anemia at 8 weeks but it was negative.
