If your Dr. tells you there is no embryo - WAIT!
Lots (and lots) of times, you cant see the embryo (just the sack) on the ultrasound and the Dr. will advise a D&C. So many women will tell you that a Dr. didnt see the embryo and weeks later, they were able to see the embryo and the baby was fine. My point is not to rush to getting a D&C or expect a miscarriage. Hope for the best. Check out this website:

I would not worry about the heart being there until at least nine weeks... many people do not see a heartbeat on the ultrasound until then.
No, by this stage the fetus should be clearly visible. The yolk sac is visible from 5 weeks.
If you were pregnant the developing embryo would be about the size of the head of a pin. The embryo is not the first sign of pregnancy found on ultrasound; the yolk sac shows up long before the embryo is visible. The yolk sac can't be seen uon ultrasound until at least four weeks after the last period.
"Yoke sack" comes from the term "yolk sac," and is a membrane that encloses the yolk of an egg.
The white around the yolk., The yolk is the embryo.
Yolk or blood are food for embryo .
It's a sack and not an egg but the primary food source, the only one, is the placenta and the nutrients go via the umbilical cord.
no the yolk is what the young chick eats.
The yolk is there to nourish the growing embryo.
The embryo, which in a fertilized egg is a tiny speck attached to the yoke sack.
Embryo is formed in germinal spot of yolk .
A fertilized egg's yolk provides all of that embryo's nutrient, it also provides protection to the embryo. There are two types of yolk, white yolk and yellow yolk, both having their purpose.
The embryo is the yolk and feeds what would be the white of the egg if cooked.
