Ultrasound 6w5d

7 weeks today and had my first ultrasound.

Baby is measuring 6 weeks and 5 days and had a very faint heartbeat. My OB prepared me for a miscarriage just in case due to the faint heartbeat. Looking for similar stories where everything was okay at the second ultrasound a week later. Next ultrasound is next Friday to hope we have a stronger heart beat.
