This situation needs treatment.  Levothyroxine should be given to keep the TSH in the 0.3-2.0 range during pregnancy.  At this point, would likely give 100mcg daily and recheck in 3-4 weeks to make sure T4 and TSH are normalizing.  Overall the risk to the baby is very low, but treatment decreases the risk even further.

Target TSH in pregnancy is 1 - 2.  They should also test FT3 and FT4 to get them in the upper half of the reference range.   Latest guidelines show benefit in treating even 'subclinical' hypothyroid early and agressively during pregnancy.

Hope you can get treated ASAP.  It is important for the baby's development and your health during pregnancy.
