Hypo or Hyper?!

I do not know what to believe anymore. According to the blood tests, I'm supposed to have hypo-thyroidism, but the ultrasound shows that I have hyper-thyrodism? What is going on? My GP suggested nuclear imaging to investigate the problem further but doing so means delaying the embryo transfer till next year! A radioactive dye will be injected during the imaging and we cannot risk having it done with an embryo inside me. Yet, if my thyroid condition is not sorted out, my GP thinks it might affect the IQ of the baby. Sigh, a bit of a conundrum there. Let's see what my gynae has to say. Meanwhile, I'm just going to try to enjoy my Perth vacation (tomorrow!!) and deal with this when I'm back.
