1 mildly enlarged kidney 20 week scan

Anyone had a similar experience?? After my 20 week scan, the doctor told me that one of my girl’s kidneys is slightly enlarged (3.9mm). He said it could be just a temporary thing that clears itself up, but he also said enlarged kidneys can be a soft marker for DS. I wasn’t expecting that at all. All other anatomical measurements were normal and not flagged. I haven’t had the DNA testing yet because my insurance wouldn’t cover it as I’m not 35 (28) and had no previous abnormalities (FTM) or family history of defects. Now that there’s this almost-abnormal measurement, I qualified and had the bloodwork taken today for the DNA test. The dr kept stressing that I shouldn’t worry, but of course I am. I won’t find out the blood test results for about 7 days. Has anyone else had something like this happen?
