the EDD is the estimated date of delivery, with both of my children the edd was not correct. my first was born a week after the edd which was the date of conception plus 40 weeks. my second was born 10 days prior to the edd but i also had 4 different edd.
Estimated Date of Delivery is just that, Estimated. A baby can be born from 3 weeks before up to 2 weeks after with no problems.
With my first, his scan EDD was 10 days later than my period EDD and he was born on the scan EDD.
Second time around (twins) the scan and period EDD were the same but I was induced 4 weeks before with pre-eclampsia.
The only EDD that is accurate from an ultrasound is one done in the first trimester. The earlier the ultrasound is performed, the better. We measure what is known as the crown-rump length (the measurement from the top of the head to the baby's backside), and this measurement is the most accurate in predicting an EDD. First trimester ultrasounds are typically accurate within a week of how far along a baby actually is. Second trimester ultrasounds are up to two weeks off; and third trimester ones are up to three weeks off. What we are measuring, though, is how far along the baby really is--not when the baby will be born. As someone else mentioned, a due date is only an estimate--and only 5% of women actually deliver on their due date.

What else can I help you with?
Can your last menstrual period show twenty three weeks but your ultrasound show twenty seven weeks which is more accurate?
ultrasound is more accurate. Measurments of the fetus are made during ultasound that give a more accurate gestational age

If an ultrasound at seven weeks on October 25 predicts a due date of June 3 when did you conceive?
When the doctor counts you as 7 weeks, they are counting from your last period. I figured if the ultrasound says 7 weeks, that is from around sep. 7th, the 1st day of your last period. meaning between sep. 18th thru sep. 24th could have got you pregnant. Likely the 21st. However an ultrasound of 7 weeks on 25th October gives you a due date of 13th June not the 3rd. See the Related Link for "conception-calculator" to the right for more.

If an ultrasound at week seven shows a low heartbeat of 70 can you still give birth to a healthy baby?
Yes, absolutely.
Will you miscarry if an ultrasound at 7 weeks 5 days only said 5 weeks 5 days and there was no heartbeat?
If they say you are still pregnant then you probably are. Seven weeks into the pregnancy is nothing. You have to take into consideration that they are going by your last menstural period when you could not have been pregnant so in actuality they are adding on a few weeks. Don't worry about it and try not to be stressed because stress is horrible for your unborn fetus.
