Wildly fluctuating TSH levels

[Guest guest]

Hello all,

I recently got some TSH test results back and am

really concerned. I am trying to get pregnant so my

thyroid doc wants my TSH between 1 and 2. And

apparently, he is unable to keep it in that range.

In April, I had my TSH done when I was alternating

between 50 and 75 of Synthroid daily for about 2-3

months. My TSH had fluctuated within the normal range

and then suddenly shot up to 2.9.

So he switched me to 75 daily. I was ok the first

month of testing, my TSH was 1.2. Then I went this

month after being on it for 2 months and it is down to

0.45! So now he wants me to go back to the

alternating. But I am confused. Is it normal for your

thyroid to fluctuate this wildly? If he has me go back

to alternating, won't it go back up to 2.9 again? Why

can't it stable out? I feel like I have tried all

options of this medication! Any light you guys can

shed on this for me would be appreciated. Thanks!

Also my T3 and T4 ranges are in the higher range of

normal that the lab sent back.
