8 week ultra sound, no baby

Becca • Dance and theater teacher, who loves cheese, being outside, and fuzzy socks. Beyond excited for my Rainbow Baby after a miscarriage earlier this year.
Went for my first ultrasound at 8 weeks today. They said I'm measuring at 6 weeks because they couldn't see the baby. They want me to come back in two weeks. But I feel like they are just waiting to see if I will miscarry naturally. I'm heartbroken. Anyone else gone through this?
