At 14wks there's an error margin of +\-2 wks. since my first sono i had 3 diff sono showing same due date in july could it be wrong i'm due in june?

Prenatal dating: First trimester ultrasound very accurate in dating. You are probably due in july. However, you may deliver in june because women don't deliver on their due date exactly... May be early, or even a little later.
