W hen Sarah Carter was pregnant with her first child, she started digging into the research on ultrasounds, scouring studies in mice and rats. Then, she heard something that compounded her concerns. After an ultrasound, a friend of a friend was told her fetus had a limb malformation. Carter decided to refuse every ultrasound while pregnant.

When her birthing center told her an ultrasound was mandatory to deliver there, she found a new provider.

Ultrasound results can dictate whether a woman needs to give birth at a certain kind of facility, so that specialists are on hand to care for the baby after birth.

Some often encountered skepticism, while others more frequently cared for women who were on the opposite end of the spectrum: getting far more ultrasounds than they needed at new standalone clinics that offer 3D and 4D scans.

The limbs and the yolk sac, though obviously important, are not the primary means of measuring growth. An average length of the embryo at 7 weeks is anywhere between 5mmmm. The average weight is less than 1 gram. Obviously, every pregnancy is unique and individual factors influence the size of the embryo at this early stage, and the embryo shows development week by week. The ideal time for a sonographer to assess the gestational age in the first trimester is between weeks of pregnancy.
This is the period of time which provides the most accurate assessment. Generally, ultrasounds which are performed in the first trimester are within days of being accurate in terms of assessing gestational age. This is because although every little embryo is unique, there are still defining characteristics of development which apply to all embryos at particular stages of early gestational development. As the embryo matures to a foetus, individual genetics and growth factors influence its growth.
This is why an early pregnancy dating scan, rather than one done in the later stages of pregnancy, is considered more accurate when assessing the expected date of delivery.
