First trimester scanning is useful to identify abnormalities in the early development of a pregnancy, including miscarriage and ectopic pregnancy, and provides the most accurate dating of a pregnancy. Technique First trimester scanning can be performed using either an abdominal approach or a vaginal approach. Abdominal scanning is performed with a full maternal bladder, provides a wider field of view, and provides the greatest depth of view.
Vaginal scanning is best performed with the bladder empty, gives a much greater resolution with greater crispness of fine detail. In circumstances where both approaches are readily available, the greater detail provided by transvaginal scans usually outweighs other considerations, and is preferred. The patient is scanned in the normal examination position dorsal lithotomy with her feet secure in stirrups and her perineum even with the end of the examination table.
Place a small amount of ultrasonic coupling gel on the tip of the transvaginal transducer. Then cover the transducer with a condom. After lubricating the vaginal opening, gently insert the transducer into the vagina. Visualize the longitudinal plane of the uterus sagital section and evaluate its’ size. It can be measured from the cervix to the fundus, AP diameter, and width. Normal uterine volume is less than cc nulliparous patients and less than cc multiparous patients.

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.

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.
