Dating behind?

Hi ladies

Had my first ultrasound today and baby is dating about a week and three days behind! There was a steady heartbeat, so I know baby is fine for now. Doc said I should return in three weeks to check whether the heartbeat is still there. And now I am worried.

Did any of you date behind and still had a healthy pregnancy?
