5w5d ultrasound measuring a week behind and empty

I’m 100% sure of my dates and had an early positive at 9dpo, so even if I wasn’t sure I couldn’t be more than 1-2 days off. I should have been 5w5d but scan is showing an empty sac and a week behind. My progesterone is a little low but only a little and my Hcg is high. I’m going back in a week for a follow up scan. I need honest opinions, is there any hope?

Thank you
