Did I Ovulate Late ?

Okay guys so Im up driving myself nuts reading my ultrasound report because to me its all over the place.

For starters my LMP was May 17th so as of today I should be 7w 3d, but on the ultrasound report the date that I had it done I should have been 6w 4d BUT it stated I measured at 6w 2d.

Another thing the babies crown rump length was 0.8cm which would measure exactly 6w 4d.

Now heres the interesting part they stated my due date as Feb 23rd, at first which in that case I would be 7w 3d. BUT then changed the date to Feb 27th which would make me only 6w 6d ?? Im just so lost at this point honestly.

When the heck did I conceive !! How far along am I ??!
