Figuring Due dates

How do doctors figure due dates?  If i calculate from LMP on 2/14 - I would be due on 11/20.  However, if I calculate from ovulation/conception on 3/12 I would be due on 12/3.  Which one do doctors usually go by?  I used the due date calculators to figure these and they are 2 weeks apart.  Just wondering if anyone had any input...

Yeah, they go by your last missed period.
It sounded pretty stupid to me.
But oh well, atleast I know I'm pregnant, y'know?
lol.

I'm due October 10th.
If they went by actualy conception, my baby would probably be due somewhere around Halloween. lol.
Which would be pretty cool cuz I love Halloween.
But I guess what the girl above said makes sense.

Your dr. will go my your LMP (To be up front~ they doesnt care if you know when ovulation/conception was, because every month your body start to get ready for pregnancy.)
