Hard to know: Early ultrasound in pregnancy can sometimes be inaccurate because a fetal pole needs to be big enough for the ultrasound technology to pick up. Typically we expect the gestational sac to grow between ultrasounds and the development of a fetal pole over time as well. No development of fetal pole could indicate very early pregnancy or blighted ovum ...Read more

Does seeing a yolk sac mean fetus?

Does seeing a yolk sac mean fetus?

No: Seeing a yolk sac only lets us know that at least the pregnancy is in the right location within the uterus and not in the fallopian tubes. To confirm that it is a good, viable pregnancy, you will need a follow-up scan in a week or two to show the fetal pole with a heartbeat. The fetal pole/fetus is not the same as the yolk sac. ...Read more

I only saw a yolk sac at 6 weeks is it possible im not as far as my LMP says i am?

I only saw a yolk sac at 6 weeks is it possible im not as far as my LMP says i am?

Yes, that's possible: Yes, the ultrasound may be correct, as many women do not ovulate at precisely day 14. You see big changes pretty rapidly in an embryo that young. Of course clinical correlation with your blood HCG levels, symptoms of pregnancy and timing of intercourse need to be considered. If you have no vaginal spotting or bleeding and if you have symptoms of pregnancy that's a good sign. Recheck in 1-2 weeks. ...Read more

Early ultrasound: When is your next scan? It is reassuring that a sac and yolk sac were both seen. A follow up ultrasound is appropriate. ...Read more

Can a embryo hide behind a yolk sac?

Can a embryo hide behind a yolk sac?

In a sense: The yolk sac is visible before the embryo grows large enough to be seen. As the fetus then grows the yolk sac will disappear. It is more a matter of timing than anything being hidden. ...Read more

Is it normal 2 only see a 15mm gestational sac and yolk sac 6.2weeks?

Is it normal 2 only see a 15mm gestational sac and yolk sac 6.2weeks?

Yolk sac: This may not be normal if you are not off on your dating. It could represent a miscarriage. However, if you are off on dating, you can do another ultrasound and/or have your doctor perform a series of pregnancy tests at least every 48 hours apart. Either or both (preferably) can help give you an answer. Normally, the blood test numbers will go up by 50% in a 48 hr time period. ...Read more

Was told i was 7w5d, could see yolk sac but no embryo? Could it be a miscalculation or should I worry?

Hard to say: Without being there or seeing the scan. If you had a vaginal ultrasound it would be quite unusual to not see a fetal pole at 7+ weeks. With an abdominal ultrasound (thorough the belly) i'm not surprised at all: they arent terribly good for first trimester. Check with your OB and good luck. ...Read more

Uncertain: The yolk sac should be visible on transvaginal sonogram with an 18mm gestational sac diameter, so this may possibly be abnormal. Check with your doctor, follow up ultrasound might be helpful. ...Read more
