I have been having weight gain, lack of energy, moody, hair breaking & etc. I had bloodwork done by my PCP back in July 2012. They told me my thyroid was good. My gynecologist noticed my thyroid slightly enlarged the other day & I have been having heavy bleeding he is looking in to. He set up a thyroid sonogram for me next week. In the meantime I called my PCP to ask what my levels were for the thyroid test last year. My T3 was 32.3 Isn't that considered very low?? Could that be a factor in all my symptoms & a few more?
