What Is More Accurate Edd You Lmp Or Early Ultrasound
Very premature is a condition in which a baby is delivered between 28 and 31 weeks' gestation. Depending on how premature, how sick, and how lucky or unlucky a baby is, he can get brain problems, cerebral palsy, blindness, deafness, developmental problems, learning disabilities, severe lung diseases, infection and loss of some intestines, etc... Babies who are only moderately premature usually ...Read more
So everyone says early ultrasounds are more accurate then LMP so mine has 4 day difference between edd so should I not go by ultrasound due date ?
Within 4 days is : No real difference. There is nothing magical about either date, except for 2 things: 1. If the lmp is different from the early OB us dating by more than 2 weeks, the lmp is probably wrong. 2. What everyone wants to happen is appropriate interval growth - meaning the fetus grows in size to match the time since the last us - that means growth is happening normally. ...Read moreSee 1 more doctor answer
Is early ultrasound at 8w1d more accurate at predicting conception than LMP? EDD changed going by ultrasound now too...
Possibly: Ultrasound done early is much better than LMP dating for the "Expected date of Delivery." Conception is another issue entirely. Usually conception occurs 2 weeks prior to a missed LMP, but this is ONLY an estimate. Conception dating is not something that is useful in medicine and there is too much variability to do that kind of dating, Unless you are an In Vitro (IVF) pt. Then you know for sure. ...Read more
I am using conception calculators should I use the due date or LMP i had a very early ultrasound at 6 weeks which is more accurate? :)
It depends: If the difference between the two is less than 1 week, use your lmp. If it is more, use the ultrasound dates. ...Read more
Edd is 11/12 based on early ultrasounds & lmp. Possible i conceived on 2/7/13? How long is sperm viable in a woman?
So are ultrasounds more accurate in the first trimester at 8w1d? And should I trust if I know my LMP & doctors change EDD going by u/s now??
First trimester u/s: The earlier an ultrasound is done, the more accurate it is. An ultrasound done at 8weeks and 1 day is probably a day or two off. This is the reason for assigning a due date based on your early ultrasound. It is probably only a day or two off. Remember, a due date does not mean that you will deliver right on that day. ...Read more
If my early 6 week ultrasound puts my edd four days after my edd from lmp, which one should I go by, my ob/gyn says ultrasound what do you think?
Had a dating ultrasound i was 14w3d. Couldnt use LMP i was on depo,I wasnt having periods. Can edd be off by 2w3d at 14 week ultrasound.How accurate?
Unlikely: 14 week ultrasound is on the cusp between first and 2nd trimester. First trimester ultrasound usually accurate to 3-5 days. Second trimester accurate to 1-2 weeks. So at 14 weeks I would doubt the dates would be 2w3d off. This would be more likely in the third trimester. ...Read more
My DD is according to 1st trimester is 13 nov latest ultrasound suggests edd 31 October.i don't know my LMP. Kindly suggest does delivery can b early?
Delivery date: Your due date is a marker for when you turn 40 weeks. This is not the same as the day that you will deliver. Normal delivery occurs between 37-42 weeks. A first trimester sonogram is very accurate for due date calculations. The due date is not changed by a 3rd trimester sonogram. ...Read more
Is u/s dating in first trimester more accurate that going by LMP? EDD changed & going by ultrasound now...
Depends: 1st trimester US is accurate within 5-7 days so if it differs from your LMP due date by more than that then the US is used. Also if you are uncertain about your LMP, most OB's will use that early US. ...Read more
The sonogram is a test that looks at body organs with no radiation. It uses sound waves and can give us a 2 dimensional view of organs such as the kidney, liver, heart, and lungs. It can define spaces that are either solid or full of fluid. I can also guide large needles into an organ or near the spine, and can help define the area being cut open. Its a ...Read more
