A member asked:
Today i have a scan which show 5 week 6days gestational sac 18.4mm but no yolk sac is everything fine?
A doctor has provided 1 answer
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.
