It sounds Hypo , But It could be doing this thing called waxing and waning... meaning sometimes it is normal and sometimes it is out of whack. Since Thyroid is an auto immune it can very , esp when your body is under stres or if you are fighting any other sickness/illness. It also could be Hashimotos.... Antibodies could be present on a tuesday..and attack you thyroid then on the next tuesday there be no sign of them..then 3 weeks later they appear....What is you Dr saying? You should keep a journal of all your symptoms..even if they seem minute..examples are cansitpation..urinating alot, excessive thirst..so on.. Hope you get some answers!
