Perkins also has extensive experience working in home health with medically fragile pediatric patients.Before the advent of routine ultrasound in pregnancy, medical personnel estimated a baby's due date by the date of the last menstrual period and by feeling the uterus and determining the size to see if it matched the given due date.Ultrasound has become so helpful that obstetricians now refer to the time before it was used routinely as “the olden days.” We use it to diagnose twins early on; we use it to document appropriate growth as the pregnancy progresses; we use it to determine fetal health; and we use it to guide conversion of breech to vertex (head-first) position and to guide amniocentesis.Of all of these uses, dating the pregnancy is the most common reason to use ultrasound, particularly when the expectant mother cannot remember the date of her last period (as in breast-feeding or irregular cycles).If the gestational sac reaches 16 to 18 millimeters and no fetal pole is seen, the pregnancy may be abnormal, according to the APA. Later measurements that don't reflect the date given by an early CRL means the pregnancy isn't growing normally, not that the early CRL was wrong.Once the fetal pole is seen, the crown-rump length (CRL) of the embryo can be measured. Once the CRL reaches 5 millimeters, the heartbeat should appear, the APA states.
