I have the opposite of McIrish's situation going on right now.
Back in March '11, my TSH level was over 5.0, so my old RE put me on synthroid, which I stayed on until July '12. I never asked for my TSH results while with my old RE, but now know from records that it had gotten down very low, like < .2, while cycling. (Is there such a thing as too low?) But, when testing for our DE cycle, while still on synthroid - I was at 2.08. Just tested again last week, after 9 weeks off of synthroid - and it was 2.89. My current RE said they would test again when I start Delestrogen.
If you've had varying levels, how often do you get your TSH tested during a cycle? Are there any dietary/lifestyle changes that affect TSH?
