My wife's LMP was 23rd july. We came to know about pregnancy on 5th of september. We did USG which showed 7.8 mm gestational sac without foetal heartbeat and it said 5 weeks and 4 days pregnancy. I.e on 5th september. Now yesterday my wife's TSH report was more than 60. Which I rechecked in same laboratory by giving another sample. At present my wife is not having any complains. Can it be hypothyroid or it might be false report? If she is having hypothyroidism and its already over 6 weeks can it have adverse effect on baby's development? Can baby come with problem of mental retardation or something else?
