Hi Dima,
I apologize for the delay. Took my computer along on our camping trip and my wireless connection didn't work. Hope to be all caught up here by tomorrow.
It does look like you have Graves' disease although when it develops in the postpartum period (after miscarriage or delivery) it often resolves easily. With your levels as high as they are you do need to be on meds to bring FT4 and FT3 back in range. TSH will stay suppressed for a long time, and a low TSH doesn't mean you're hyperthyroid while on treatment.
I agree with the endo that the meds shouldn't have been stopped. But since you were euthyroid based on the FT4, your dose should have been reduced to 5 mg daily. It's true that your levels will likely return to normal within a few weeks. Because it usually takes 6-8 weeks for levels to return to normal, perhaps you could ask your doctor to have labs sooner perhaps at 4-6 weeks rather than 2 months. You could also use the 10 mg dose and if you notice any symptoms of hypoT, call the office and report them and ask to have labs then. Since your endo's advice is fairly standard, I wouldn't change endos at this point.
Symptoms in Graves' disease can be very vague. While many symptoms are associated with GD, most people develop a few predominant symptoms and these can sometimes be so ordinary they're not noticed. Some women have scant or absent menstrual periods, mild irritability, increased appetite, and a mild euphoria that makes them feel more energetic. Also, back when TSH was low and thyroid levels were normal, it would have been common not to have symptoms since subclinical hyperthyroidism doesn't usually cause symptoms. Best, Elaine
