Thyroid us 0.6cm hypoechoic nodule & 1.2cm partially cystic nodule.going to endocrinologist but can't get me in for a few weeks. reason for concern?

Safe than Sorry: Since the lesions are at least partially solid, the endocrinologist will probably want to be more safe than sorry. You will probably require a radioactive iodine scan of the thyroid to evaluate the nodules more closely to see if the nodules are truely only cystic, or he/she may elect to perform a fine needle aspiration of the lesions to collect samples to be tested under the microscope.
