Your
TSH of 2.75 is within the normal range for this stage of pregnancy, where the usual target is generally below 3. Total T4 naturally runs higher than the non-
pregnant range in pregnancy, since pregnancy raises the protein that carries it in your blood. Your 11.94 reading fits that pattern too. Together, these two values don't point to a
thyroid problem at 20 weeks.
Next Steps
Keep taking any supplements your obstetrician has already prescribed. Please discuss this with your obstetrician at your next antenatal visit, so they can confirm it fits your overall pregnancy picture.
Health Tips
Let your obstetrician know if you notice unusual fatigue, a racing heartbeat, or sudden weight change before your next visit.
