Kinda upset about news from my anatomy scan.

Brianna
Yesterday at 18 weeks and 3 days I had my anatomy scan and I work in labor and delivery and look at ultrasounds all the time... I could tell something was wrong when she got to his kidneys. I asked her "are you going to tell me what's wrong or the doctor" she asked how I knew something was wrong I was just very disappointed she wasn't going to tell me at first til I caught her. 
His kidneys are supposed to be at 1mm and my baby's are 6mm and 4mm meaning he's retaining fluid and his kidneys aren't filtering properly. So I will have to go back and see a specialist and see if they are resolving by the self.. Has anyone gone through the this with another pregnancy and what was your experience? 
I know I'm told not to worry it's common in boys but as a mother I worry about everything. Easier said than done.
