A member asked:

What should be my due date? 1 ultrasound report says that its 11 january but other says that its 20th january 2015 my lmp is 3rd april 2014(irregular)

A doctor has provided 1 answer

Earliest: The earliest ultrasound is the most accurate and I would rely on that since you say your periods are irregular. The margin of error (how many weeks plus or minus) for ultrasounds increases as pregnancy progresses. All 3 day embryos are pretty much the same size but babies at term can be normal and be 6-9 pounds.
