Pregnancy math can be a little murky. After all, unless you went the IVF route, your physician has no way of knowing the exact time of conception. Because of this, pregnancy is calculated from the first day of your last menstrual period or LMP. From that day, weeks of pregnancy is officially counted, and your doc or midwife busts out the red pen and marks your due date on the calendar. Sometimes, however, the due date may be revised. It can be pretty difficult to determine a due date using the date-of-last-period method for women with irregular cycles — which is why an ultrasound exam is often required to determine gestational age.
An early ultrasound, usually done at about 6 to 9 weeks, can give the most accurate due date estimation by measuring the size of the embryo or fetus. However, many pregnancies are confirmed by a Doppler heartbeat monitor, not an ultrasound. Did you get your very first ultrasound in your second trimester? If so, that could be why your due date shifted. Ultrasounds performed during the first trimester not the second give the most accurate due date predictions, according to a study in the American Journal of Obstetrics and Gynecology.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.
By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.

Throughout my pregnancy , I’ve received two different due dates — one came from my very first ultrasound, when my baby was barely the size of a blueberry, the date that was then subsequently stamped on my record as “the” due date. But then there was a second date, the one that showed up on my next couple of ultrasound scans. This date was a few days earlier. It’s also the date that I prefer, not only because I’m now 38 weeks pregnant and ready to get this baby out, but because it matched the date I’d calculated on my own using information I looked up.
And how much does it really matter? After all, as many moms know, due dates are just educated guesses.
Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in Transvaginal scans usually provide clearer pictures during early pregnancy and in obese women. Dating is more accurate when done earlier in the pregnancy; if a later scan gives a different estimate of gestational age, the.
It is common to be given a single ‘estimated due date’ EDD which corresponds the point at which it is estimated that your pregnancy will have lasted 40 weeks. It may be more helpful to be prepared for you baby arrive some time after 37 weeks, and to focus on 42 weeks as the time by which you have a good chance of having given birth. Many women with longer pregnancies find that everyone is asking whether they have had their baby yet, and that health care workers start to suggest inducing labour.
For some women this will be the right decision, but it is important to know that this is your decision to make. Charting temperature, monitoring mucus, using ovulation test kits and knowing times when you could have conceived, or having conceived by IVF may mean you have your own information about when you became pregnant. There is a tendency for midwives and doctors to talk as though the EDD written in your maternity notes is something definite, rather than an estimate which may or may not be accurate.
In that case, if the EDD is later than it should be that could mean that the birth is delayed unnecessarily. This suggests that in general ultrasound dating is more accurate in predicting the birth date than counting from the last monthly period 1,2 but it is still only an estimate and may not always be accurate. A recent study 3 of women who conceived by IVF and therefore knew when their egg was fertilised, found that the routine ultrasound dating scan consistently put their estimated birth date earlier than it should have been by an average of 3 days.
In any case, ultrasound does not give a very accurate prediction of the actual birth date. Dating from ultrasound scans done later than about 20 weeks is increasingly less accurate.
