Hi Yukti,
Thanks for posting in HCM.
I understand your concern.
One thing what you need to understand is that
miscarriage has happened as a result of high
TSH levels and not the other way around.
Since your T3 and T4 levels are normal and only TSH component is elevated, it can be categorised into 'subclinical hypothyroidism'.
By taking the prescribed medication, if you keep the TSH levels under normal limits, it would improve your chances of conceiving as well as minimise the chances of miscarriage.
Also, after conceiving, you need to continue with medication and keep a constant check to keep TSH, T3 and T4 levels within normal limits, as alteration of which would affect
pregnancy as well as growing fetus.
Kindly follow the instructions as given by your doctor and do the necessary follow-up as advised.
Hope the information provided would be helpful.
All the best.
Regards,
