Look on the web: There are standard tables on the web, available for you to see to determine gestational age based on crown rump length. This crl is truly the best way to determine a persons true gestational age and due date, up to about 14 weeks pregnancy. Fetus's do not vary in size at 14 weeks gestation. They are all the same size. After 14 weeks, consider looking at the bpd or femur length.

Not really: That would be average for about 14 weeks.

Not necessarily: The fetus is not always visible by 5 weeks. In my practice I would suggest another scan at 7 weeks and I would check to see if the hcg level is rising and I do progesterone levels as well (not all OBs do progesterone levels). While a blighted ovum or missed abortion is possible in your case, it is too early to confirm that based on your information.
