First appt today: doc says I'm only 7w2d!

I honestly thought I was further along.. I mean not by much but at least 8 wks! Glow said I was as well. I'm just confused tho bec I was given due date of July 6th which would make me 7w 2d as the doc said but my glow profile has me back at 7 wks exactly.. It's off by a two days.. Ugh any thoughts/advice? Btw here's my u/s!
