Bubble in 20 week scan

[buttonnosebear]

Has anyone ever had a bubble floating near the baby's mouth in a 20 week scan? And if so, do you know what it means or is?? On the photo it looks about as big as baby's hand (but is not)
Thanks

Are you sure it's a bubble?

how do you know it's a bubble? those things aren't that clear lol
you could ask your midwife

Did the sonographer say anything?

What do you mean bubble what colour is it if it is obvious they would have said something prob just a pool of fluid - takes years to become a sonographer wouldn't try and read it yourself IMO!

Yes it's a bubble, the sonographer mentioned it, btw, it's my sister-in-law's baby (their first after years of trying) hence them not remembering what the sonographer told them about the bubble! I think she said it was were the baby had swallowed the fluid - anyway, my brother isn't at all worried as he is on a high since day one of pregnancy! I just wondered if anyone else had a bubble too as I didn't with either of mine.
