Team Pink or Team Blue

Hi everyone,

have has my 12 week scan at 12 week 1 day.
The sonographer said she cannot make out anything.
We have 2 girls and hoping for a boy this time.
Attached is the spine shot but I cant see the nub there, any guess?

Thanks to all in advance

From what I can see I lean girl but it looks cut off so take that with a grain of salt.

Could be a boy as there is a bump on top there but really not the best pic to see:/
