Hello I am 33 years old unmarried girl, I feel tired, exhausted all the time since I get up in the morning till I go to bed. I get short of breath when I walk fast or trying to go by stairs. Aslo my menstruation duration is very short. Its only one day bleeding and next day my periods are over. So can you please tell me whether I am going through the iron deficiency, if I am so what should I do to get the rid of my problem and what medicines should I take for this. Please advise.
