Based on LMP and my cycle length (27 days, very regular), my due date is anywhere between April 9th and 12th. ;-) The little wheel says the 12th, while online calculators give me all of the dates in the above range.
However... I think I ovulated relatively early in that cycle (based on CM etc.), and we were DTD all week, since we wanted a better shot at having a girl... so I think that probably all of those dates are relatively "late."
When I count the 269 days of average gestation from the date I think I most likely conceived on, I get April 12th, which is also what they're using in the dr's office, so I've been cool with it.
I've had a "feeling" about April 11th for a while, but that's tomorrow, and aside from some crampiness and being an emotional wreck (which I can put ENTIRELY down to insufficient sleep, topped off by a trip to the zoo this morning and a preschooler who skipped his nap), I'm not "on the way." I expect this to be a long, slow labor (assuming I ever GO into labor... never did last time; got dragged there by a pit pump and my body just never got into it), so I don't think baby's b-day will be 4/11 unless things start happening in the next couple hours.
If I get to 42 weeks, I honestly don't know what I'm going to do. I think unless I have a truly excellent Bishop's score, I'm going to just go for a repeat C at 42+1. :-/ I know my body isn't much for induction, and it would have to be even more gentle than last time anyway due to the scar on my uterus. (42 weeks is *my* comfort zone, btw... don't really know what my doctor's is; he asked me first and didn't volunteer anything after I spoke up.)
