Hello! After having carefully reviewing your discussion , I would like you to advice the following
1) Your USG is absolutely normal & you are being able to feel fetal movements at fourth month implying a normal going pregnancy
2) Your TSH
is high , 9.62uIU/ml suggesting hypothyroidism
although the T4 & T3 level appear normal'
3) So, you are required to reconsult your gynecologist & also have a consultation with an endocrinologist
to be investigated further & managed accordingly, in view of the BOH.
Thanks & take care of yourselves!
