There is not regular consultation?? Are you nuts?
You are childhood
thyroid patient and because of this negligence not because of doctor but because of patients like you your baby is at full risk to get hypothyroidism.
And you blame doctors in the end .
Immediately raise your thyroid dose to 150mcg ( probably u will require 200 dose )
Get
TSH every 45 days and increase till normalisation
Your baby will requires thyroid tests his birth don't miss it get him screened and supplement to be given to him if required.
Its so late u r in 9 months u and your husband is very ignoring person and not caring much for your health may cost u in future.
Kindly be wise and keep a touch with good Physician near you.
