Doctor Wants to Follow Up on 10 Week Ultrasound

I got a call today from the doctor's office that the doctor wants me to come in tomorrow to discuss test results.

About a week ago, I went for a 10-week scan to check on a small SCH that was discovered on the 6-week scan. I thought the scan went fine, the tech showed me fetal heartbeat, fetus was measuring 2 days ahead, and the SCH had disappeared. The tech even asked if I wanted to take some pictures so I thought that was the end of that.

Now I'm worried sick abt what could be wrong so early in the pregnancy?
