Boy or girl nub

[RAMLMiles]

hi I have added two images below
One is my 12 week scan and one is a scan at 14 weeks.
to my eye it looks like a girl nub in one and a boy in another but I’m not great at looking for nubs.
can anyone shed any light or guess what I am having from these scans?
thanks for your help

May be easier to compare in this pic x

Hi ladies, I had my scan today 13 weeks tomorrow, just for fun wanted to know what everyone thinks by the nub theory thing I can’t seem to understand it or know what I’m looking for! Thanks 🥰

I think both girls as nub is more horizontal than vertical!
