Welcome to HCM
Thanks for posting query to this forum,
You are known case of Hypothyroidism
and pregnant again during lactation
as already 2 months.
Your HCG is high then a Ultrasonography
to confirm and get examined by Gynecologist for follow up.
Your TSH is definitely high especially due to early pregnancy
as dose required in Pregnancy is more.
It is true dose may have to be required but please consult Physician /Endocrinologist
In Hypothyroid state due to physiological changes we need to monitor FT3,FT4 and TSH carefully.
Please do not increase the dose by yourself, but continue to take your supplement regularly and follow up with Gynecologist regarding proper monitoring of growing Fetus.
