Are you sure you didn't forget to record a BD? The scan dates match up with what could look like ovulation on your chart but then it is very unlikely you conceived from the earlier BDing.
My guess is you have ovulated earlier near one of the attempts and the baby is measuring behind. I really wish it wasn't the case as I had the same problem with my 2nd m/c as it was only measuring 5w 3d at 7wks. Although I had a BFP earlier when you still had BFNs so I'm a little baffled by your situation.
Unfortunately it is just a matter of wait and see. Fx everything works out ok!
