I had my 20 week ultrasound two weeks and ago and my baby's kidneys measured 3.8 and 4 mm and the doctor reassured me over and over that he isn't conserned at all and he fully expects my baby to be 100% healthy. He thinks she probably just had to pee during the US. He scheduled me for another US at 28 weeks just to recheck everything. My friend made me feel nervous about the US bc she isn't having another one and so I went to my enemy, the Google. Now I'm afraid it's a soft marker for Down syndrome and her kidneys are enlarged and she isn't going to be healthy. Anyone had this and it been fine? I have severe anxiety.. Obviously.
