I tend to get very exhausted and run down after and during my periods where I am able to walk without getting out of breath i have had my iron levels checked last month and they were ok but with this my periods tend to very i.e. very heavy sometimes. I really don't know what to do I don't want to keep having blood tests or having iron tablets. doctors are not helpful and my diabetic nurses do not have any advise on this. any advise on how to make myself feel better will be great
