Hi, I recently posted about my thyroid detection in my pregnancy. I read on internet that baby entirely depends on mom thyroid in first trimester. The sad part is we could only detect that I had hypothyroid post 13 weeks. We are little concerned about baby's brain development etc. is there anyone on this forum who have been in the same boat ? How was their experience? Where there any issues with the baby at all? Do you know if this fact is just a small risk or happens often with people?
