Pregnancy dating

In other words, it dates the pregnancy, on average, two weeks longer than it is.

The other way of measuring the dates of the pregnancy is to measure the fetal age.

Having a scan in the first few months of pregnancy can be a thrilling experience.

It's amazing to see the little blob with a heartbeat that will soon become your baby.

The whole point of the scan is to work out how many weeks pregnant you are.In fact, the Cr MS dating correlated, on average, in the following way: Cr MS ETA = U/S, ETA 1.97 days.The Cr MS dates were highly accurate with the two being within 10 days of each other in 100 percent of the cases. Here, a pregnancy occurring in a longer cycle where the Peak Day occurred on Day 26 of the cycle is shown.An accurate date for the beginning of pregnancy can be established with the use of the Cr MS.This correlates well with the ultrasound dates and the estimated due date or ETA.
