What Causes An Empty Gestational Sac During 5th Week Of Pregnancy?

Posted on Thu, 8 Jun 2017

Question: Hello. I had a transvaginal ultrasound performed when I was (estimated) 5 weeks pregnant. The gestational sac was found and measured 9 mm. I was told this could be a blighted ovum as a yolk would typically be seen at 8 mm. However, I have a retroverted uterus. Would this make it more difficult to see a yolk this early in my pregnancy (giving me hope for a viable pregnancy) or is it likely to be a blighted ovum?

Brief Answer:
You should wait ...

Detailed Answer:
Hi, dear and thanks for your query to HealthcareMagic.

I have read your question carefully and understand your concern.

In fact, at 5 weeks of gestational age in the transvaginal scan, we should see a yolk sac.

But in my practice of Gynecology, I have had patient as you in whom I haven't seen a yolk sac on 5 weeks of gestational age but when they came after one week I have seen a yolk sac inside gestational sac.

Hence, in my opinion, you should not worry too much and wait one week more and do another transvaginal scan.

Hope I have been helpful and please feel free for further discussion.

Best regards
