Mine was still visable at 13 weeks, Im not sure when they go away....I had my 20 week anatomy scan last week and I didnt see it nor did they point it out, so I guess its gone..
Thanks pmperez, So at some time between now and my 20 week scan it should go away. I guess it stays active until the placenta is fully functioning on it own.
I just had my 8 week and ultrasound and saw the yolk sac. they told me it was kinda rare to see so i was getting alittle worried. I never say one with my first child at all and we did our first ultrasound at 71/2 week with him. i am glad to hear it is not that rare.. thanks for posting
Mines disappeared between 6 and 10 weeks. It wasn't visible at my 10 week ultrasound
i had my first ulrasound at 9week and did not see a yolk sac is that ok
