My doctors sent me to a nutritionist at my last appointment (29 weeks and a day). They're concerned with my weight gain and worried that the baby might not be growing as much as he should. I'm on Medicaid and go to a health department. Could I probably ask for another ultrasound to check growth? Would the ob I see for my next appointment be the person To ask? They give me whoever is there so I don't have a separate doctor to call. I live in North Carolina btw.
