Hello I can understand your concern.please try to relax. Do not blame yourself for anything. Take the positive aspect that you got yourself evaluated and have been diagnosed early. You have been started on thyroxine supplements. So do not worry. As you are majorly worried about the effect on your child, I would like to quote the conclusions of 2014 EUROPEAN GUIDELINES for management of hypothyroidism in pregnancy. Conclusions • Current data indicate an increase in pregnancy loss, gestational diabetes, gestational hypertension, pre-eclampsia and preterm delivery in women with SCH in pregnancy. • The association between SCH in pregnancy and impaired neuropsychological development of the off- spring is inconsistent. Maternal hypothyroxinaemia is associated with impaired neuropsychological development of the offspring. Basically, there some studies which suggest that there is a possibility of neuropsychological impairment but no consistent results.. Whatever is done is gone, so better would be if you follow your medicines properly and have a tight control of your TSH  values.
