Original Author Legend

"The size (2cm in length) and anatomic features suggest development equivalent to a nine-week pregnancy (GA 9 weeks or post ovulation 7 weeks). In obstetrics, pregnancy is dated from the first day of the last menstrual period, which is about two weeks prior to the ovulation that resulted in the pregnancy."
