I don't know much about the baby getting hurt, but it is good that they are checking your thyroid levels. If there is a problem you and the baby will be closely monitored. The greatest risk comes from untreated thyroid problems. Like I said, it's good you're getting your thyroid checked. Sorry that I couldn't be much help...the blood results should definitely arrive this week and you and the endo will be able to talk more about you and the baby..
