Borderline AFP results


Hello everybody, I am currently pregnant with my rainbow baby, due January 25th. I just got my AFP results back, and they were 2.25. It says normal is below 2 and elevated is above 2.5. I don't have an anatomy scan for another week. I had an early one at 15 and 3 and everything was fine. Doctor already wrote in my chart that I would have weekly ultrasounds after 28 weeks, which makes me think it is a bigger deal than it sounds. She said on the phone she was being overly cautious but wants me to see the high risk doctor. Anyone have any experience? I didn't do genetic testing with my son.
