Once you have the actual TSH and T3/4 results please do post them here and we will be able to help you better !
It is good that you performed a thyroid US, it will show whether you have nodules and their sizes , if it/they are big enough then a fine needle aspiration might be recommended by your doctor.
More than 95% of nodules are benign, so you should not be worried, also the size of the nodules is important but also their shape, this is why you should ask your PCP to refer you to an Endo.
Best of luck,
