Thank you for everyone's reply - sorry if i had you also stressed out. I saw my endocrinologist today ( 2 weeks was a long wait) and said that she thinks the obstetrician got confused with Graves disease - apparently there is a problem with antibody transfer to the baby over the placenta. But with Hashimoto's as long as your levels are within the normal range things will be fine. So i'm more relaxed now. I'm 19 weeks today and my TSH is 0.4 im feeling great and she is happy with everything

All the best with your pregnancy and birth just around the corner.
