As you are taking a combinatiin dose of T4/T3 therefore your T4 will be low due to the combination. As you are taking a combination dose, the doctor should also have checked your Free T3 and your FT4. Your T4 is low because you're also taking T3. Blood tests were introduced for levothyroxine (T4 only). Before that our symptoms took priority. Levo (T4) is an inactive hormone and has to convert to T3 but you are also having additional T3 so I wouldn't be too worried. This is from TUK:
I'm just worried it might effect the baby if it's not supposed to be that low.
I knw I will get a call from the antenal endocrine now 😏
Would you recommend I increase my dose or the numbers look ok? I mean I still feel so tired yawning during the day and need a nap without fail.. even prior to pregnancy so won't really say it's entirely related to it.
