Hello ma'am and welcome.
I would like to say that most women with PCOS
have an associated thyroid
abnormality. This fluctuates during the year. Now what could have caused the sudden rise in your TSH
levels needs to be investigated, but clearly clomid
cannot have such an effect.
Also, as you are on clomid I am assuming you are trying to conceive soon, please make sure your thyroid profile is regularized before you do so.
Hope this helps.
