Portable ultrasound

V • Mama to Silas (12-19-15) & Rosie (10-27-18)
At my 11 week ob appt yesterday we had to use the portable ultrasound machine because the main one was being used and he said the quality isn't as good. I didn't really see any movement and he said he saw the heart fluttering but I couldn't see that either... My question is, has anyone had a doctor use poor quality machine and not be able to see movement but everything was okay?
