Longer Cycle Ladies- was your due date accurate?

Dalva
I've always had 34/35 day cycles. Not sure exactly when I ovulated. According to my doctors and ultrasound baby is measuring right around (plus or minus 1 or 2 days) my EDD based on the standard 28 day calculation but I'm worried that regardless my due date could be way off.
Ladies with longer cycles- do your due dates reflect that? Second time moms, was your baby born before, on, or after she date?
Thanks!
