Just want to hear expieriences, ultrasounds?

Question

I am pregnant, and my last missed period was Nov. 18, 2006. So when i went to my first dr. visit they told me my EDD was 8/23/07, then i had my first ultrasound done, at what we thought was 18 wks, but the baby is measuring only about 16 wks, which would change my EDD to 9/7/07. I understand that the EDD is just that estimated. But my question is at 16 weeks or 18 weeks how accurate is this ultrasound, which date do you think is more accurate. I could have concieved either weekend, so im not sure.

Thanks for all of your help mommies!

Answer 1

generally the ultrasound EDD is more accurate, since it is based on measurements...but it is still an estimate...your baby could be measuring larger or smaller than the average.

Answer 2

I would go with your last period. If they were pretty regular. The farther along you get the less accurate the ultrasounds are in determining a due date. It can be pretty accurate in most cases, but they are more accurate in the beginning of pregnancy, like the first trimester. A baby can either be bigger or smaller then expected and not always measure consistently. Also your doc will measure you at each visit now and can see how you compare with your due date.

Answer 3

the ultrasound date is usually more accurate, but now always, go for august 23 that is the birthday of all my children, a 4 year old and 2 year old twins. GOOD LUCK!!

Answer 4

the ultrasound could be off as much as 40%, witch is alot when talking about little babys! they told me my daughter was 4 pound at 9 months and i needed a c section... she turned out to be 7pounds 9 oz
and i delivered naturaly. if you go to http://pregnancy.baby-gaga.com/
and put in the date of your last menstration it will give you an accurate look at the size and weight of your baby

Answer 5

My due date changes with each u/s, then ended up going back to my first one. Its just a guesstimate
