Hashimotos. Was fine on 25mcg synthroid, (thyroxine) now suffering from fatigue, muscle weakness, and body aches. Could there be another cause or my pregnancy?

In brief: Yes

Thyroid hormone levels can change during pregnancy.
You should check to be sure your TSH level is normal.

In brief: Could be either

Early pregnancy is very frequently associated with fatigue, which generally goes away by the second trimester. On the other hand, pregnancy is often associated with increase in the dosage required to maintain normal thyroid levels.
Usually this occurs later in pregnancy, but it would be worth having your thyroid status checked to be sure your current dose is correct.
