All those dates are within the normal range of error. Due date based on LMP is plus or minus 2 weeks. based on 10 week US is plus or minus 7-9 days. based on 20 week US is plus or minus 14 days.

And yours were all within 8 days of one another Perfectly normal. Oh BTW, Due date has little if anything to do with DELIVERY date. You will deliver when the baby pushes the button.
