Due date

I have zero idea when I’m due.

My LMP was June 24-27. Got a BFP July 22. So that puts me at 6+2. US tech said (before doing ultrasound) that I’m 5+4 but Doctor said my sac is measuring 6+5. So I have no idea how far along I even am🤷🏻‍♀️ didn’t see a heartbeat today or a fetal pole but saw yolk sac. I go back in a week. Any ideas/thoughts?
