13wk 3days, excited, but is there any indication of gender?

This is my 4th baby, really happy :)
I was just wanting to know if there is an actual nub on this pic or is it just a line? Also, if it is the nub, what gender are you's thinking....

thanks xx

The nub is very flat for 13 weeks, but the stacking at the end is throwing me off. Guessing 60/40 girl

Just a guess, I say girl :-)

I lean pink but that little bulge has me a wondering a little

boy guess

Pretty clear nub, looks quite girly to me.

I dont know why but i'm guessing boy because of the end

Thank you for the guesses :)

Pink

Very slight boy lean.
