I had my 1st appt & US on June 29th. Based on LMP they said 8w3d and put my DD at 2/5. But w/US, CRL said 7w6d which matches w/when I ovulated and puts DD at 2/9. Since I am VBAC and they insist on sch a c/s one day after DD I am insisting they go by when I know I ovulated whcih is supported by US. So officially my EDD is 2/9. I will be 10 weeks on Tuesday. 2nd trimester here I come :)
