What size should the SAC be at 5 weeks?

Gestational Sac, Yolk Sac and Fetal Pole The gestational sac may be recognized as early as 4 weeks and 1 day from the last menstrual period and should always be seen after 4 weeks and 4 days.

Can fetal pole develop late?

The fetal pole is a thickening on the margin of the yolk sac of a fetus during pregnancy. It is usually identified at six weeks with vaginal ultrasound and at six and a half weeks with abdominal ultrasound. However it is quite normal for the fetal pole to not be visible until about 9 weeks.
