Which sonogram is more accurate 7 or 18 week For example at 7 weeks you were 7 weeks and 3 days At 18 weeks you were 19 weeks 7 days Which is correct?

Because an ultrasound at 7 weeks and one at 18 weeks use different methods for estimating gestational age, they have different levels of accuracy. In general, a skilled sonographer's 7 week ultrasound is more accurate for dating than a skilled sonographer's 18 week ultrasound. Talk with your health care provider for information specific to your situation.

How accurate is a sonogram?
A sonogram is 100% accurate, insomuch as it's basically a picture. Interpretations of that picture may vary, and may or may not be accurate, but the sonogram itself is a sounding of whatever is being examined, incapable of being "inaccurate."
Would there be any reason to have a sonogram at 4 weeks?
I always have a sonogram at 4 weeks or earlier. I have a history of ectopic pregnancies.
Can a sonogram miss a twin at 15 weeks?
Yes.
You are seven weeks sonogram said you were five weeks do i need to feel concerned?
No. It is very hardly to accurate say how far along you are. Just make sure that you have everything ready for labour (not for a while yet) and don't leave it to the last minute
When they do a sonogram can they know exactly when you got pregnant?
If the ultrasound is done in the first weeks of pregnancy it is possible to date the embryo within a few days, an ultra sound done later is not as accurate for dating purposes.
If a level 2 sonogram is taken at 19 weeks and the head measures at 19 weeks but legs measure at 18 weeks could this mean a birth defect?
Did you ask your doctor or sonogram technician this question? I do not believe that it would indicate a birth defect. My son had short legs (and still does). I wouldn't worry, but I would ask the sonogram technician to explain. Good luck :)
Baby femur measures 24 weeks and pregnancy is 26 weeks?
Go with the sonogram unless you have absolute knowledge.

Either you are not pregnant or you are less than 5 weeks pregnant.

You mean with a Sonogram? They can make mistakes but not very often.
Can a doctor tell you are pregnant by a pelvic exam as early as 5 weeks?
There is no point in doing a pelvic exam at 5 weeks. A sonogram will show if you are pregnant.
How soon can an internal sonogram show pregnancy?
An internal sonogram can show pregnancy as soon as 4 weeks. There will likely show an amniotic sac which is the first to form during pregnancy. Within a week after that you can see the fetus start to form. The heartbeat will likely show around 8 weeks.
