A little concerned....

Ga

Today at my doctors visit, I see him every two weeks due to the fact that I’m having di-di twins (B/G). As it turns out, in my 20 week ultrasound they found what seems to be a cyst in my son’s (Baby A) left kidney, I have another specialized scan with a special doctor this Thursday, as of right now it seems to be just one cyst and it could also be calcium instead, but I’m just concerned and wondering if any other mothers out here have had the same thing happen and how it turned out. Much thanks.
