Could I have hypothyroidism?

I received lab results back, I go once a year to get my labs done because I am anemic and I try to monitor that yearly. Anyway, I am not a doctor and I know google isn't either, however, I am hoping someone in the Yahoo Answers community can help me out. I feel that I have hypothyroidism. I can't lose weight no matter what I do, I am always cold, I have cramps and aches all over my body (although they aren't so bad I can't handle it), I get headaches, my hair seems to be falling out more, my skin is dry no matter how many bottles of lotion I rub on it and I have irregular periods. I know other things can be causing these symptoms as well but my lab results show my TSH level is 2.42 and my T4 free is 1.03. I also know that the range of "normal" has changed from .5 to 5.0 to now .3 to 3.0 for the TSH level. As I said I am not a doctor and I don't pretend to be one which is why I am asking all you intelligent people. I have an appointment with my doctor on July 12th and I want to make sure I ask the right questions to get the right answers. Thanks so much for all of your help everyone!!!
