7 weeks measuring 2 weeks behind

I’m suppose to be 7 weeks 5 days based off of my last period. Today I had my confirmation ultrasound and all we saw was a gestational sac measuring at 5 weeks 3 days. I have a history of MC so of course my mind is going to the worst.

Has anyone else measured behind and have a positive outcome? Trying to stay hopeful though I’m pretty sure I know how this will go.

Next ultrasound is in 2 weeks to see if we have any growth. I’m still experiencing all my pregnancy symptoms. Now we wait.
