Confusing ultrasound

Shelby

I got my first ultrasound today. I am 6 weeks 5 days and baby measures 6 weeks 3 days. Heart rate of 108. My ultrasound tech didn’t say much and my Dr. wasn’t in today. I don’t know what these are supposed to look like but right now I am SO scared my gestational sac is too small? Can anyone help me? Im terrified.
