An ultrasound is a highly accurate means of dating a pregnancy. In a normal pregnancy, ultrasound can provide an estimate of the gestational age to within five to seven days of accuracy. In the first trimester, doctors usually use a transvaginal rather than abdominal ultrasound. The transvaginal ultrasound provides the most accurate information, given that the early developing gestational sac and fetal pole are extremely tiny at this point.
A transvaginal ultrasound can get closer to the developing pregnancy. In a transvaginal ultrasound, the doctor or technician inserts a thin probe into the vagina. During the ultrasound, they take a series of measurements, including the size of the gestational sac, the size of the yolk sac, the length of the fetal pole, and the heart rate. In an abdominal ultrasound, the woman will be asked to come to the scan with a full bladder, because this positions the uterus in a way that makes it easier to obtain measurements.
The doctor or technician then spreads a gel over the lower abdomen and uses a transceiver to take measurements from a number of angles. These are averages for when specific early pregnancy developmental points become detectable by transvaginal ultrasound. Generally, abdominal ultrasound is less sensitive and may not detect these milestones until a week or later in the pregnancy. Remember that any uncertainty about the date of ovulation could affect what the ultrasound will show at any point in early pregnancy.
The results of an ultrasound are compared to what is expected for the gestational age of a pregnancy.

Barring the incredibly meticulous, tracking the exact time of conception can be, at best, a guessing game.

Obstetric ultrasonography , or prenatal ultrasound , is the use of medical ultrasonography in pregnancy , in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus womb. The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus.
The International Society of Ultrasound in Obstetrics and Gynecology ISUOG recommends that pregnant women have routine obstetric ultrasounds between 18 weeks’ and 22 weeks’ gestational age the anatomy scan in order to confirm pregnancy dating, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy, and to assess for congenital malformations and multiple pregnancies twins, etc.
Performing an ultrasound at this early stage of pregnancy can more accurately confirm the timing of the pregnancy, and can also assess for multiple fetuses and major congenital abnormalities at an earlier stage.

The pregnancy is calculated based on the average menstrual cycle which is 28 days. The first day of menstrual bleeding marks the first day of the menstrual cycle. Right in the middle of this picture perfect 28 day cycle is when ovulation occurs day 14 of the cycle and roughly 2 days before and after is when you are most fertile. This is why many fertility doctors recommend to have intercourse every 3 days if you really are trying to have a baby because the ovulation may occur a little earlier or later than you may think.
When calculating the weeks of pregnancy we include those two weeks from the first day of the LMP as this is the easiest part of the cycle to notice and to record. We also will enquire about the length of your cycle and whether it is regular or irregular. All of this is helpful in trying to establish the gestation. For example, if your cycle is regular and 33 days long we would expect your ovulation to have occurred later 5 days and an early pregnancy scan will most likely show a baby that measures 5 days less than you were expecting.
Now to answer your question, it may be that you ovulated later in the cycle or have a longer cycle. The other possibility is that unfortunately the pregnancy is not developing as expected at 7 weeks gestation and a follow up scan may reveal a miscarriage.

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.
Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation. This is because the fetus is growing so quickly that there is a big difference in size from week to week. However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment.
The EDD from the early dating scan is used – if the last menstrual period is not known or is unreliable, or the dating scan differs from the last menstrual period dating by more than 5 days. Ultrasound examinations from 12 to 22 weeks are regarded as being within 10 days of accuracy or up to 10 days earlier or 10 days later than the woman’s calculated due date. Ultrasounds performed after 22 weeks gestation cannot be used to estimate the due date of the baby because the size no longer reflects the age very well.
Even average babies can differ by up to 2 to 3 “weeks of growth”;.
