Nub guesses please! 12+3

I have three pics, not sure if any are a good view. Would love some opinions! Thanks!

Any thoughts? Is the bright white line the nub? What about that forked looking thing in the top photo? Thanks!

If that's a nub I see on the second picture, I think maybe a girl. Congrats!

I don't think I see a nub

Possibly girl

Thanks all! Hoping for girl but will have to wait and see I guess!

I think girl also

I found one more shot I hadn't posted. Not sure if it helps :)

I go with girl too, but not 100%.

Any more thoughts? I find out Thursday morning! Which pic are you seeing the clues in? Thanks!
