Help with gender prediction - 12 week scan!

Hi all!
My friend recommended me here to help me predict the gender after my 12 weeks scan Monday (I was 12+6).
What are your thoughts? Any predictions very welcome!
My friend sis said that you lovelies predicted both her and her best friend correctly! X

I'm no expert but can't pick out a clear nub in your pic to make a guess from sorry.
