Ultrasound confusion

Lacey

So I went for my ultrasound today and am supposed to be 9 weeks but the tech said my sac is measuring 6 weeks 6 days and that there’s no fetal pole so I’m assuming that means I’ll be miscarrying right away? Has anyone else gone through this. My doctor wants me to go for another ultrasound in a week cause she has hope but I feel like there can be no hope if there’s no fetal pole. Am I wrong?
