3 hr glucose test

I just finished my 3 hr glucose test and when I left I got a call from my high risk drs office saying they was told by the dr that I need to do another ultrasound but when i was told I wouldn’t need to go to them anymore. The dr did check my fundal height and baby’s heart rate but didn’t indicate anything was wrong so I’m confused. Think the two could be related?
