Some say it is a boy depending on nub theory, what you think?

Up! I appreciate all thoughts above. My question is if there is no nub, what is that thing that looks like a nub in the first two pictures?

Here is another picture I just found.

Guessing boy from the last pic[emoji1]

Thank you Molly for your guess!

Up! I'm still curious. If there is no nub in the first picture, so what is that thing that looks like a nub? What about last picture? I have ultrasound next week, but I am looking for more guesses from you!

Maybe boy from last pic. First pic might have an outline of the nub, but it isn't clear, so not reliable to guess from.

Thank you Claire33 for your reply!
