Gestational sac size

When is the very earliest you would be able to see anything on an ultrasound? I am talking days after conception

You should be able to see something anywhere from 4-6 weeks.Hcg at about 1900-2000

Hi, I'm sorry my cycles are not 28 days. Do you know about how long after conception?

[megku]

Is that based off of a 28 day cycle?

[Heather5]

4-6 weeks means about 2-4 weeks after conception.

[megku]

So you would say about 14 days after conception. Do you happen to know what the measurements would be? I think I read somewhere the earliest you could see anything on an ultrasound was 4 wks 5 days

[Heather5]

That sounds right. By 5 weeks or so, is when you can expect to see something...so that would be about 3 weeks after conception. But for some, it's closer to 6 weeks (4 weeks after conception).

[maybrie]

That's probably true but not all women and pregnancies are the same some can't see anything that early. Are you pg? How far along are u?

[megku]

Well, I am 24 weeks now. But I early in my pregnancy, I had an ultrasound at 4 wks 5 days and it showed a gestational sac measuring 8 mm, and what looked also like a yolk sac. I just thought a measurement of 8mm was a little big for 4wks 5days

Don't know about that. But if you're fine now, then what is the problem? Is your baby measuring big/small?

Usually you can see something or a sac at 5 weeks.
