Urine in baby’s kidneys 20’weekz

Shannon

Hey guys I had my 20 week anatomy scan today. She kept measuring the kidneys well the doctor informed me his urine was backed up in his kidneys BUT that it was nothing to worry about that this happens mostly to boys and is VERY VERY common... well I’m a worry wart I wish she wouldn’t have told me that. Ofcourse I looked it go online and I read several stories where this occurred and it either cleared up before next US or after birth.... but I also read where it’s a soft mark for downs!? Has anyone had this happen to them and there baby actually have DS? We got tested for it and it came back normal at 11 weeks. I’m so worried I pray my baby doesn’t have downs. Anyone help me with this?
