Can a ultrasound be ten weeks off if you think your 12 weeks and ultrasound reads your 22 weeks?

Ultrasounds are fairly accurate - a fetus at 12 weeks is very small. A 22 week fetus is fairly large. They measure how big bones are, and the distance around the head. There is no mistaking a 12 weeker for a 22 weeker.

Can an ultrasound at fourteen weeks be off by two weeks?
Yes
At 18 and a half weeks pregnant can an ultrasound read at 20 weeks what would be the reason Is the baby big can an ultrasound be off by 10 days?
At this stage, yes the ultrasound can be off by 10 days. Mine was off by ten days the other way, that is I thought I was 18 weeks and the ultrasound said 16 and a half. I knew when I had conceived because my husband had been away on a trip.
My ultrasound puts me at 21 weeks preg that would mean I was feeling movement at 14 weeks took cheap home test at 3 weeks now measure 26CM and not sure of LMP could ultrasound be off by 3 or 4 weeks?
my ultrasound said that my last period was nov25 could it be right
If an ultrasound said you were 9 weeks one day which means you were 7 weeks one day can an ultrasound be off by 10 days from that in the first trimester?
I think all ultrasounds these days are pretty accurate. If you have doubt you could always go to another clinic for a second opioion. Good luck
Why are 2 weeks taken off your ultrasound scan age?
Because it's about 12 days of conception
I Should be 7 weeks but ultrasound says 6 could my due date be off?
It is unlikely that they would be that far off. They're often off by a couple of days or weeks, but not usually 1 1/2 months off. I strongly suggest that you speak to your doctor about it for more information.
How many days out could a scan be?
An obstetrical ultrasound can be as much as 1-2 weeks off, before or after the due date.
Your doctor says that you are only 36 weeks but the ultrasound says the baby already weighs 8lbs7oz your other kids were all pretty small is this normal or could they be off on your due date he also s?
36 weeks is 9 months, you are full term. due date could be off by a little but i think you are about ready to go.
8 weeks pregnant went in for ultrasound saw sac but no baby now have to wait for another week for another ultrasound is it normal to be off on the weeks pregnant?
it is called a blighted ovum if your counting of the age of gestation is correct and yet no baby is formed except of the sac. on the otherhand if you are not sure of your counting then do an ultrasound 1-2 weeks after your first ultrasound to see whether the baby develops or not at all. just cant flawlessly explain the blighted ovum. check out on the web or much better ask your physician.
If an ultrasound says you are 25 weeks 4 days pregnant when in fact conceived 25 weeks 2 days what date should be relied on?
If you know when you conceived you should always go by your date. Ultrasounds, especially later in pregnancy, are not as accurate. Here are the dates that they can be off. The inaccuracy of ultrasound First trimester: 7 days 14 - 20 weeks: 10 days 21 - 30 weeks: 14 days 31 - 42 weeks: 21 days
My first ultrasound was done at 16 weeks and 2 day and I was woundering if a ultrasound done at that far along was acurrate in deteriming how far along you are or could it be off by like 4 weeks?
I'm assuming you wnat to know this because you are unsure as to who the father is? Please, forgive me if I'm wrong though. Ultrasounds can be inaccurate by a margin of about 2 days. There's no way they could be off by as much as 4 weeks though! Sorry, I hope things work out for you though!
