So confused-sneak peek vs nub

So my 6 and 8 week scans were predicted girl by the gendologists and I agree they looked girly,I did the sneak peek clinical at 9 weeks which also came back girl,then yesterday I had a scan at 12 weeks and 3 days and to me the nub looks boyish as it looks slightly risen? A few people guessed girl but I didn't think girls nub rise at all? I'll add a pic let me know what you all think x
