5.3 weeks, 0.8 cm gestational sac, no fetal pole and no yolk sac

Hello Anonymous,

Welcome to EmpowHER. Thank you for reaching out to us with your questions. As much as I would like to help you, I am not qualified to assess or interpret the findings of your most recent ultrasound.

These are all important questions. I suggest you write them down, and ask your obstetrician during your next visit. Schedule the repeat ultrasound as suggested. Continue to take good care of yourself.

I can offer you general information.

The fetal pole is a thickening on the margin of the yolk sac of a fetus during pregnancy. It is usually identified at 8 weeks with abdominal ultrasound imaging, and 6 weeks with vaginal ultrasound imaging.

The yolk sac is membrane-lined sac that provides nourishment in the early stages of a baby's development in utero. It also acts as a rudimentary circulatory system before the embryo is able to circulate blood internally.

For these first few weeks in your baby-to-be's development, he'll be nourished by the yolk sac. The yolk sac provides all the nutrients the embryo needs and produces blood cells until the placenta fully forms later in the pregnancy. Toward the end of the first trimester, the yolk sac shrinks and can no longer be seen on the ultrasound.

Anonymous, it may have been too early in your pregnancy to see the fetal pole and yolk sac.

Keep in touch,
Maryann
