ultrasounds are a better judge, in an ultasound it measures the baby to see how big it is and then it is fed into a chart that will tell you when the due date is, the chart is based off of what size the baby should be at that week and day.
You must have given them two different guesses on your last period date. But the hospital would be more accurate.
Women have cycles that are not all the same length but most women ovulate 14 days before a period is due. That is what makes the difference. At 7 weeks ultrasounds are accurate to within 3 days. At 20 weeks they are accurate within 5 days When I had my first pregnancy my cycle was 36 days which would mean my EDD would be 8 days early if my LMP was used, my US agreed with my cycle not my LMP. When I had my second pregnancy my cycle was 28 days and my ultrasound agreed with my LMP. So you are saying that the ultrasound is more accurate? Yes, the ultrasound is more accurate. I did go round the houses a bit to say it.
The ultrasound date is approximate and based on the size of the baby, but if you go back exactly that far it would be Sept 21.
It would probably not be accurate since it is testing for the hormone HCG and you should wait until your period is due in anther 2 weeks to test again for accurate results
If you are on your period is unlikely you are pregnant. Ask your GP if you are concerned.
The conception day would be 11/18/2008, based on you're due date. You're due date is more accurate in the early stages of pregnancy. SO if you got an ultrasound in you're first 12 weeks, it is pretty accurate. Good luck sweetey!
That means it is the date conceived (or within 48 hours of). It is never right on, but within a week of. Go by what the ultrasound says. No, if your ultrasound says 17 weeks and 2 days that would be that date plus 2 extra weeks, that is around the time of your last period, unless you have irregular periods or conceived straight after a miscarriage or something. The length of pregnancy is always measured from your last period even by ultrasound.
Well we just went to see the doctor about my fiance who according to her last period should be roughly 16 weeks along. The doctor said she was showing signs of being more like 20 weeks. My fiance's last period was late and light, and on further thought could quite possibly have been a false one. The doctor said when we go back for the ultrasound next month that we would be able to tell more accurately what the actual age was.
An ultrasound machine would require an ultrasound transducer. These are required as they are the part of the machine that delivers the image to the machine.
That would be a good question for your doctor. The doctor might suggest an ultrasound. From the ultrasound picture, the technician can estimate how old the fetus is and predict your due date.
The ultrasound dating has excellent and precise estimation of gestation especially if done in the first trimester (first 12 weeks). After 12 weeks, its accuracy goes down. However, compared to dating according to menstrual cycle, the ultrasound would be more accurate.
If you were pregnant the developing embryo would be about the size of the head of a pin. The embryo is not the first sign of pregnancy found on ultrasound; the yolk sac shows up long before the embryo is visible. The yolk sac can't be seen uon ultrasound until at least four weeks after the last period.
