Sack but no baby

Ki

So I had my first appointment today. Which left me with more questions than answers. They did an ultrasound and I thought I was six weeks and two days or so. The ultrasound showed a gestational sack but no baby. They didn’t seem concerned but I’m going back on the 14th for another ultrasound. They think I’m about five weeks now I’m just nervous I can use some reassurance. ❤️
