Ultrasound at 14 wks-B or G nub and skull guesses please!

Hi,
Expecting my first child in August. These are my only ultrasound pics so I'm hoping you guys can help me predict the gender via nub or skull theory. Please share your guesses and why you chose B or G. I'm trying to sharpen my prediction skills. Thanks in advance!

Based on skull (so just for fun) guessing boy xx

Thanks Mulberry Smurf! I'm so anxious for clues. I hope to get more guesses!

Can't see a nub and I'm clueless on skull theory but such a cute baby- congrats!

The pictures are too small to see a nub, maybe if you post just one but bigger? Good luck!

Thanks Yahmama and aidansmom! I will try to post them separately. Please more skull guesses in the meantime...thanks. So excited to give my scan update in 2 weeks!!!

Full size scans for better guessing...hope this helps!!!

Any more guesses?

Thinking boy.

Thanks maidentomother! I have been feeling like a boy the whole time although the Chinese calendar, baking soda, and cabbage test all read girl. Of course, I now these tests are just for fun! Did you guess using nub or skull theory?
