Stacking or a girl nub????

[Shansch]

Is this stacking or a girl nub at 13 weeks?? I have other images where the top line is much longer, but in all my photos the bottom line is more prominent and longer than the top line. Does this indicate a boy or girl?

Looking at the shape and angle it's looking girly, but it's not the best pic

For that gestation i'd say girl.
