A single live fetal pole is referring to the baby in the stage when it is first visible inside the gestational sac. As for the intrauterine gestational sac, that is means the pregnancy is seen within the uterus and is not ectopic.
I believe it means that they have only seen one sac--as in one embryo...not twins.
this is a hard question! :-l sorry!!!!
If you blood work is positive , give it a couple more weeks .
The protective sac around the embryo or fetus is the amniotic sac.
It was difficult to see the line that represents the very beginning of the embryo. Most likely, the gestational sac was seen on the ultrasound.
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
It usually appears after 4 weeks
about the size of a pea
That sac is called as amniotic sac.
