I based it on both: I O''d on CD13, which makes it likely that conception was CD13/14, then with a 14/15 day LP I reckoned FF''s guess was close enough.Date: 9/8/2008 2:56:43 PM

pandora - when you got your EDD, did you base it on your LMP or O date?
Why don''t more HCP''s base it on O-date rather than LMP for those who chart and know the exact O day?
If you have very long/irregular cycles it is a lot harder to pinpoint ovulation, so they date from LMP as people can remember that one - then they date the baby at the 12 week scan.
Does seem strange - for example is it the case that:
Person A has a 28 day cycle and a 14 day LP. They ovulate on CD14 and 14DPO they get a BFP.
Person B has a 42 day cycle and a 14 day LP. They ovulate on CD28 and 14DPO they get a BFP.
A & B troop off to see their doctor. Person A is told they are 4 weeks pregnant and Person B that they are 6 weeks pregnant whereas they are both only really 2 weeks pregnant?
Hmmm.
I have everything crossed that I can cross for you Mela - good luck to all the others knitting (I''ll cross everything I can for you guys as well)!
