34 weeks pregnant doctor app tomorrow.. its so hard to catch my breath i get dizzy. could it be due to my iron anemia? or could it be something else

Dizzy and shortness: of breath could be dangerous symptoms this far along in pregnancy, especially with anemia. You should be seen as soon as possible. Good luck.

Appointment tomorrow: Good thing you have an appointment tomorrow. Pregnant women often describe a mild shortness of breath. This is called dyspnea of pregnancy. Have your doctor check you out tomorrow to make sure that all is well.
