Is there any nub? what about skull theory?

I'm guessing girl

BOY!

I don't see any clues.

i dont see clues sorry

Thank you ladies..... I am soooo hoping for a boy. But I have a gut feeling that it is a girl. I will be happy either way. I am 15 weeks now.... will schedule an appointment for 20W ultrasound pretty soon. I can totally go to an elective place ( only 99$) but I am just so nervous about finding out gender. I am worried about gender disappointment.

not sure I see any clues.

thanks Inky. So what is that white thing in the bottom? I thought that was nub.

Maybe boy?

Maybe boy based on the new pic, but I had guessed girl before so it's 50/50 for me lol

Thanks ladies... I guess i have to wait for 20 weeks scan.

Couple days for the gender scan... any final guesses ?? may be skull theory?

I have my fingers crossed for you :)
