How accurate are dating scans at 14 weeks 100 belarus dating
In the month after my period none of the days showed as ovulating- which according to the dating scan this is when I would have conceived. hi pureapple i dont really know a definate answer to your question but as far as i am aware the dating scans go on the size of the baby so it could be wrong and your baby might just be small but i cant tell you one way or another sorry.
It's entirely based on the measurements, not on what you think you know.
I know to within 4 hours when we conceived, because it's an IVF/ICSI pregnancy.
This is my scan history: 7 3 - measured 7 3 9 0 - measured 9 0 11 3 - measured 11 2 13 0 - measured 13 2 So you can see it was pretty tight - but still a bit variable.
My GP thought at first that I was 6 weeks preg and than my scan cut the two weeks off so all a bit confusing!!!
But yet again m,any thanks for all your comments and good luck to all of you!!
If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
Is it possible that I was told that I am 11 weeks preg but I am actually 14 weeks? 2 weeks after my initial intercourse I had a period, after that I had couple of unprottected intercourses and found out I was preg.
so although I'm sure very occasionally it's not right, I really think in your case it most likely is.
I would have though that the scan is more reliable than an ovulation test to be honest, there will be some variation as as mentioned previously they are measuring size and there is bound to be some individual variation.
I was told by a hospital midwife at the scanning unit that of all those dates, 9 0 was likely to be the most accurate.
Too early, and a mm can make a difference, too late and you start to get individual differences - and of course, it simpley gets harder to measure due to position.
I think it's all really weird anyway to be honest as you count 2 weeks when you know you definitely aren't pregnant making 40 weeks which actually equals 10 months ! Well he was born at 39 wks on 2nd May so it looks like the scan was right all along.
