Hi am a 19 year old female, i am always tired, light headed, never hungry, always pail (according to my coworkers), have a bad cough and every time i cough i cough stuff up. last year the tested my iron and it was low about a 7 i think but just went to the doctor last week and they retook my blood to test and it can back as a 12 so the said that is not the reason for my symptoms.
