Resource Summary

OBJECTIVE
Alberta clinicians assign gestational age based on ultrasound biometry

TARGET POPULATION
All pregnant women

KEY MESSAGE
Ultrasound is consistently more accurate than relying on patient recall for menstrual dating
Routine ultrasound in the first or second trimester reduces inductions for post term
pregnancies
A woman’s self-knowledge and awareness of her internal functions^ including ovulation^ can be very accurate. However^ given the physiologic changes that can occur in any one menstrual cycle^ the exact time of ovulation^ fertilization and implantation cannot be precisely known.
