Hello, I was told by ZRP (Prenatal Care) that there is a growth delay in the fetus, they gave me directions to another women's consultation so I could get an appointment with a doctor. I go to the registry and say that my ZRP sent me here, but she asks me "Is it due to non-viability of pregnancy?" I am like what? I have ZRP, and she again asks about non-viability of pregnancy? Can you please explain what this means?
