Hello ladies! Im 19 weeks and 2 days and my doctor prescribed me 25mcg of medication for thyroids today my t4 is normal but my 3rd generation is at 0.093 ml. I had a natera test at 10 weeks and a maternal at 16 weeks both came negative for down syndrome, spinal bifida etc does that mean that the thyroid being low didnt affect the babys brain development? Thank you for your help and also if any of you have this and want to share positive tips or positive thoughts thank you! Really scared first time mom!
