My lmp was may 17 but my first ultrasound (6 weeks) gave a due date of feb. 24, my periods aren't that regular. when did i conceive?

If..: If your periods are irregular it is not reliable to use the date of your LMP since we don't know what was the cause of the delay in the first place( pregnancy or your usual hormonal pattern). You have to rely in that case on the US dates which could differ 1-2 wks at this point from the real dates.
