lybrate-user, If you are planning to have a baby, then it absolutely essential to have TSH at the present level (1.94 mU/L). Recommended level before pregnancy is between 1 to 2 mU/L. So now the level is right. At higher levels pregnancy is unlikely to occur. Plus during the pregnancy also levels have to be maintained around 2 mU/L, for proper development of fetus and expected outcome of the pregnancy. So you need to continue the same dosage for now. Later once pregnancy occurs there may be an increased dose needed. Which can be decided by testing the TSH levels later.
