Hi my wife is 24 weeks probably and has been on thyroid meds since the first day of pregnant as it was 4.5... After meds it had come down but now after we got it checked again and it's 7. How does this effect the baby ...till the 20 week scan in was in the range but not it is high.. Though she is on the same medicines and dosage . What could be the reason . Will it effect the baby .
