  • DD is an estimation, there is no way of knowing exactly when you conceived unless they confirmed ovulation , conception and implantation date (and usually they don't unless you are an ivf case).

  • The measurements on the screen is what they're going by. The measurements of mine said my child would be born December 7th. He came along on January 21st. Big baby.

  • Mine was the same way. 0ne was based on my LMP... the other was based on the size of my son. He was born March 11... just 3 days before his due date according to his size....

  • You can have a different date for every single measurement they take in your ultrasound. The head circumference can give you one measurement, the waist another, the leg bone another...if they were going to change your due date, they would have told you. Don't stress about it...no matter what your actual due date is, that baby is going to come when its going to come...two weeks really isn't a big gap.

  • Sono Due dates can be wrong as well, if the baby is stretched out or not stretched in a certain position. Using your LMP is sometimes accurate as well. You can also go by your conception date if you know how to calculate that. Or you can do the 240 method. You can google it and research due dates.

  • Actually the measurements taken during an US are not that accurate. With my twin boys, my regular doctor had me at one gestation then when I went to the Children's Hospital in Oklahoma City the doctor there had me two weeks earlier than my doctor. Example: my doctor had me at almost 32 weeks and the doctor in OKC had me at 29 weeks. When my boys were born at 33 weeks (the second doctors estimate), the doctors put their development and stuff at 35 to 36 weeks. So my doctor had me about right.
