5-11 Week Early Pregnancy Scan

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.

NHS and private ultrasound scans during pregnancy

In early pregnancy, especially before 11 weeks, it is usual to have a trans-vaginal internal scan , where a probe is placed in the vagina. This gives the clearest and most accurate picture in early pregnancy. The person doing the scan spreads a special gel on your lower abdomen below your belly button and above the line of pubic hair.

He or she then moves the scanner over the gel, sometimes pressing down, until the uterus womb and pregnancy can be seen. That may give some information about your pregnancy, but it is less clear than an internal scan and that could possibly delay diagnosis. There is no evidence that having a vaginal or an abdominal scan will cause a miscarriage or harm your baby.

The MSD should not be included in this calculation. For reporting pro forma examples, see First trimester reporting pro forma. Skip to main content. First-trimester ultrasound.
