Hashimotos & pregnancy ?

Kaitlyn

Diagnosed 2 years ago with Hashimotos but my TSH levels were always fine so no one has treated me with medication.

Here I am 33 weeks pregnant and my blood work came back stating my T3 uptake and Free Thyroxine Index were both really low. TSH still in normal range.

Is this something I should be concerned with? I don't see my doctor for another 2 weeks and I am not sure if not his warrants a phone call or not.
