Sorry Mildred,: those numbers are most likely related to the ultrasound settings, (Depth/gain/frequency) Ask your OB or sonographer for your dates or measurements. In early pregnancy we measure crown-rump-length (CRL). Later, the fetal head diameter (biparietal diameter or BPD) from "ear-to-ear." Also look for abd. circumference (AC), head circum. (HC), or femur length (FL) since these are used more often.
