Hello,

Thanks for your query.

Gestational age in first trimester is usually calculated by crown-rump length. At 11 weeks, it is approximately 41-54mm.

Large yolk sac is usually associated with anomalies and miscarriage. But the single measure can be a misleading factor. So do not worry.

I encourage you to get a few more tests such as nuchal translucency along with blood tests like beta Human Chorionic Gonadotropin levels , pregnancy associated plasma proteins before reaching any conclusion in this regards.

Chorionic villi sampling and genetic counseling is required if needed.

Hope my answer is both informative, useful and assuring. Should you have any additional concerns, I will be available to address them.

Best wishes

Hello.

Thanks for writing again.

To my knowledge there is no such record but I have seen one case delivering normally personally.

So just keep your fingers crossed for the best.

I would suggest you to follow your Gynecologist's advise on further investigations, as she is examining you periodically.

I hope I have answered your query.

Wish you good health.

Regards.
