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. Its diameter when first seen is about 2 mm and the normal sac increases in size to measure 5–6 mm at 5 weeks.
Can there be a yolk sac and no baby?
It contains a yolk sac (protruding from its lower part) but no embryo, even after scanning across all planes of the gestational sac, thus being diagnostic of an anembryonic gestation. A blighted ovum is a pregnancy in which the embryo never develops or develops and is reabsorbed.
Is 4 weeks pregnant really 2 weeks?

Can you get a false negative at 4 weeks?
Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.
