The only thing that could be of concern on comparing your two tests is that your hemoglobin level has dropped from 14 to 12 . This could be the reason for your dizziness . However it is improtant to state that the levels are still normal and it can vary especially after a menstrual cycle in women. I would advice you repeat the test again in a month and compare the values. The other cause of the symptoms could be a change in hormonal level and thus leading to premenstrual syndrome which could lead to similar symptoms. However if they do get worse please consult a physician in person to rule out any heart /thyroid involvement, any other source of bleeding and anemia. All the best.
