Hello Doc, I am into my 9 week pregnancy, recent ultrasound shows normal growth for baby. I could hear good loud heart beat of the baby. However, doc told to have noticed chloridecidual separation. Doc advised resr and susten 400 for the next 4 weeks, also ultrasound to be done after 4 weeks. I have normal reports this time with higher thyroid, Please guide me about my condition and about the prescription given. Also I am concerned for my baby.
