Jumping on the nub theory

[Stephanie226]

I really don't understand this nub theory so can anyone hazard a guess? x

Anybody? Is the nub even visible? I have other pictures 😁 x

Can we see the other pics as no nub is visible

I'm thinking the photos are all too similar, possibly not showing the nub in any. Oh well, need to go with the old fashioned way of waiting until the next scan 😂😂 x

I'll guess girl, even though I can never find the nub even if it's visible!
