Idk what to go by

My period was 5/15 according to the first day of my last period I would be ten weeks, but I know we didn’t baby dance til June 1st and 2nd on my last two o days, and the here and there until the 16the when I got my 1st positive test, I went in for my us and was told the sac was empty and to come back and if it wasn’t growing it stoped, I’ve currently looked at my medical records on this app my obgyn uses and they have technically determined it’s nonviable I’m scheduled for another us weds to see if it’s growing or not. But would I feel like I would really be about 5/6 weeks if we didn’t do it til the 1st week of June and then the implantation stuff takes about two weeks right I mean if all the dates adds up and stuff I’m not that far along so maybe everything’s okay and gonna be good???? Idk if any of this makes sense
