Really low TSH levels!?!

Jules
Hi ladies I am beyond worried. I just received my blood results digitally and saw that I have a very low TSH level (0.051 norms start at .3 up). The T3 and T4 levels are normal though. Anyone have anything like this?? I'm assuming I have to wait till Monday to call the doc. In the mean time I am worried sick as to what this can mean?!!
