Hypothyroidism

Last Dec during my annual check up doc suggested that i might have thyroid issue to check if possible. In March during my eighth week  visit i mentioned to my obgyn about the same and all my levels turned out to be normal. I am not on medication. Should i get it checked again it has been bothering me. She said everything looked perfect. But isn't thyroid check a routine in USA. I just wanna be sure nothing is harming my girl inside. I have my next visit in my 24th week
