Well, my LMP was July 19, and I charted my BBT as well, so I KNOW I ovulated on August 2. That gives me an EDD of April 25. That's what I
am telling people, regardless of how many different dates I get from U/S. Actually, on my 2nd U/S (20 weeks and 2 days), I got different EDDs based on different measurements! Baby's femur measured 20w 3d, baby's HEAD measured 21w 6d!!!
