Boy or girl? confusing nub!

Hi everyone!
I am desperately trying to find out from my ultrasound if I'm having a boy or a girl! I have been told a girl but also that the pic is not clear enough! I can see the nub and it appears horizontal but I am no expert! I would just love anyone to take a guess PLEASE!!

Thanks so much Xx

No nub here. More pics?
