SERIOUS QUESTION FOR PREGNANT/ MOMMAS

at our 9 week scan we discovered our munchkin has a thickening in the nuchal fold. it’s .2mil thicker than normal. my OB wants to rescan at 12 weeks and do the genetic testing at that time as well. after going to google like i’ve been told countless times not to do i discovered this thickening can mean my baby has down syndrome, congenital heart disease, kidney and urinary track issues, and so much more. but i also learned this thickening can just disappear completely out of nowhere, and doesn’t mean my baby has any of these possible issues. it’s definitely worrisome and was just curious if anyone else has seen this before with their babies!
