My LMP was also the 2nd August, but I definatley O'd 2 weeks late (I didn't know I could even O!). The latest scan by baby's measurements put me at exactly 6w3days today. Otherwise I would have been 8 weeks already.

We might have the same due date Mine is the 24/05/07

Good luck with the scan and let us know how you go!

Hugs

Naomi.
