Skull theory and question about nub

I have posted bubs picture here before bit this time I contrasted it a bit as I wasn't sure I could see the nub. Is it that lil fork looking thing just below the leg? If so I'm guessing very girly right? And my bubs skull is bloody huge. Lol. But any skull guesses? This was at exactly 12 weekshttp://i83.photobucket.com/albums/j2...psedeff2c3.jpg

I think it's the second or lower forked bit. Not the one above. Looks girl. Your baby looks more like 11.5 weeks (due to head being that bit bigger still).

Maybe still time to rise ?
