Does high TSH level affect pregnancy?
The present study showed that higher TSH was associated with miscarriage in early pregnancy. In fact, TSH levels between 2.5 and 4.87 mIU/L increased the risk for miscarriage, with TSH greater than 4.87 mIU/L increasing the risk even further.
What if TSH is high and T3 and T4 are normal?

What causes high TSH levels in pregnancy?
What is optimal TSH level for pregnancy?
The Endocrine Society recommends that TSH levels be maintained between 0.2-<2.5 mU/L in the first trimester of pregnancy and between 0.3-3 mU/L in the remaining trimesters. The aim of this study was to examine the relationship between TSH levels in early pregnancy and the risk of adverse pregnancy outcomes.
How can I lower my TSH during pregnancy?
