Hypothyroid.: If I read your statement correctly, and I'm not sure I do, you are still hypothyroid and need to stay on the higher dose. Your numbers are somewhat confusing, but with your TSH still elevated at 4.57 on 75 mcg of Synthyroid you are not corrected and should not go down despite whatever the free T4 level is. In fact if you were my patient I would have increased your dose.

Not sure of question: Due to a typo, I'm not sure what "reduced to 0.25". All other values provided seem to be in normal range. Testing on any specific day after turbulent hormonal situation of miscarriage would be difficult to interpret. Wait some more time, monitor symptoms, and work with you physician to interpret/explain follow-up thyroid testing in 2-4 weeks. Best wishes:)
