Boy or girl?? Gender scan Tuesday! :)

Hi! This is my 13 week 2 day u/s scan. We find out the gender in a few weeks, but I would love to hear of any guesses anyone may have. :)  Thanks in advance! 

from the nub theory I feel it could go either way as it looks dead on 30 degre, and havent heard of the skull but TY for your comment X GL

 Thanks! Anyone else? All guesses would be greatly appreciated!
