Welcome to HealthCareMagic,
The normal range of TSH
is 0.3-4.0 uU/ml. Your TSH is slightly high, which means your serum tT-3 & fT-4 level should be low. Thus, if your serum tT-3 & fT-4 level are below normal range, you should take Thyronorm
as prescribed by your doctor. By supplementation with Thyronorm, if serum tT-3 and fT-4 are kept in normal range, will not have any bed effect on you and fetus.
Hope you found my response to your query informative and helpful.
With good wishes,
Dr.Chandra Shekhar Sharma
