Should I be concerned about the medical tests I've been getting for my thyroid?

I had an ultrasound of the thyroid which showed a 2mm hypoechoic nodule in the interpolar region of the right thyroid lobe and a 1.2 x 0.9 x 1.4 cm hypoechoic nodule in the medical aspect of the left thyroid lobe that extends into the left side of the isthmus that demostrates punctate internal microcalcifications. I did have an ultrasound guided fine needle biopsy and am awaiting results. No one has explained what any of this means. Should I be concerned?
