A few years back mine went from 4.0 to 0.01 within a few months. I was diagnosed with Hashimoto's Thyroiditis.
My doctor reassured me and she said that if you had 4 different blood draws during one day you'd get 4 different numbers--so there's normal fluctuation even within one day (like the day I tested 0.01 it could have been .10 or 1.0 earlier or later in the day).
For the last two years, my TSH has stayed in about the 1.0 area with meditations (for hypothyroid). So, it self-regulated somehow.
I hope your Endo reassures you as well and that it's not something more serious.
