Hi,

Sounds like your endo is right on the ball and treating you properly.  Great.  Keep us updated.

Thanks for your reply.....spoke to my endocrinologist ......she advised to start thyroxine at 25 mcg per day and repeat the test after 15 days....shall keep you posted.......

Hi,

I think during pregnancy most doctors like to be conservative.

You need to ask your doctor.  A low dose of thyroid meds would not harm.  103 is mid range for T4, so they may not be concerned.

Let us know what happens.
