Thyroid and Pregnant

I am almost 14 weeks pregnant. I was diagnosed with Hashi-basedow leaning towards hypothyroidism late last year. I have been doing blood tests once per week, and in contact with my endocrinologist, and lately my TRAK is above 6. My Ob/Gyn let me know that we should do an ultrasound of the baby’s thyroid around week 20.

Since I have over a month to go, I have many questions...I guess its routine and precaution to make sure that everything is ok, but its worrying me nonetheless.

Anyone had similar experiences?

Thank you,
